De novo fatty acid synthesis occurs in the liver, kidneys, and adipose tissue. It is a multi-step process that converts acetyl-CoA into palmitate using acetyl-CoA, ATP, NADPH, manganese, and biotin. The first step is transporting acetyl-CoA from the mitochondria to the cytosol. Fatty acid synthase, a large enzyme complex, then catalyzes the reactions that elongate the carbon chain by adding two carbon units from malonyl-CoA in each cycle until palmitate is produced. While most fatty acids come from diet, de novo synthesis provides lipids for certain tissues.

The de novo synthesis of fatty acid
The document summarizes the de novo synthesis of the fatty acid palmitic acid. It occurs in the cytosol using acetyl-CoA as a precursor. There are multiple steps: (1) acetyl-CoA and NADPH are produced, (2) acetyl-CoA is transported from mitochondria to cytosol by conversion to citrate, (3) citrate is degraded back to acetyl-CoA in the cytosol, (4) acetyl-CoA is carboxylated to malonyl-CoA by acetyl-CoA carboxylase, (5) the fatty acid synthase complex catalyzes repeated reactions using malonyl-CoA to eventually form the 16-carbon
De novo fatty acid synthesis (Palmitic acid)
The document summarizes palmitate synthesis from acetyl-CoA and malonyl-CoA. Specifically, it notes that palmitate synthesis requires 8 acetyl-CoA molecules, 7 ATP molecules, 14 NADPH molecules, and 14 hydrogen ions to produce palmitate, 8 CoA molecules, 7 ADP molecules, 7 phosphate ions, and 6 water molecules. It further explains that in palmitate, only 2 carbon atoms come from acetyl-CoA, while the remaining 14 carbon atoms are from malonyl-CoA, which is produced from acetyl-CoA.
Fatty acid synthesis
This document summarizes the de novo synthesis of fatty acids. It discusses that fatty acid synthesis primarily occurs in the liver and lactating mammary glands using acetyl CoA, ATP, NADPH, Mn2+, and biotin. The first step is the production of cytosolic acetyl CoA from mitochondrial acetyl CoA. Acetyl CoA is then carboxylated to form malonyl CoA by acetyl CoA carboxylase. Fatty acid synthase is a multifunctional enzyme that catalyzes the remaining reactions. The major sources of NADPH required are the pentose phosphate pathway and conversion of malate to pyruvate in the cytosol. Palmitate, a 16 carbon
Biosynthesis of fatty acids
Fatty acid synthesis and degradation occur through different pathways. Synthesis takes place in the cytosol and requires NADPH and acetyl-CoA, adding two carbon units at a time from malonyl-CoA. Degradation occurs in the mitochondria using NADH and FADH2 to split acetyl-CoA units. Fatty acid synthesis is a multi-step process beginning with activation of acetyl-CoA followed by repeated elongation cycles using acetyl-ACP and malonyl-ACP substrates until palmitate is generated, then released by thioesterase.

BIOSYNTHESIS OF FATTY ACIDS
This document summarizes the process of de novo fatty acid synthesis. It occurs in the cytosol of liver, kidney, adipose tissue, and lactating mammary glands. Acetyl-CoA is the starting material, which is transported from mitochondria to the cytosol via citrate. In the cytosol, fatty acid synthase complex catalyzes the reactions to produce palmitic acid (C16) through cycles of condensation, reduction, dehydration, and reduction. The process requires acetyl-CoA, malonyl-CoA, ATP, and NADPH as substrates and is regulated by enzymes and hormones.

Lipid metabolism
Lipid metabolism involves the breakdown of fats into fatty acids and glycerol through lipolysis. Fatty acids then undergo beta-oxidation in the mitochondria to produce acetyl-CoA molecules, which enter the citric acid cycle. This process occurs through four steps: activation, transport into the mitochondria via carnitine shuttle, and three steps of beta-oxidation involving dehydrogenation, hydration, and thiolytic cleavage. Beta-oxidation of a fatty acid like palmitate produces 8 acetyl-CoA molecules, yielding 129 ATP through the electron transport chain in total. This allows fats to be an important source of energy through lipid catabolism.

ALCOHOL METABOLISM
Alcohol is absorbed from the stomach and intestine and metabolized primarily in the liver. The liver enzyme alcohol dehydrogenase oxidizes ethanol to acetaldehyde, which is then further oxidized to acetate. A small amount of alcohol is eliminated through the lungs, urine, and sweat, while the majority is metabolized in the liver. The metabolism of alcohol increases the NADH/NAD+ ratio in the liver, leading to metabolic alterations like lactic acidosis, hypoglycemia, and fatty liver. Chronic alcohol use can also damage the liver and brain, potentially causing cirrhosis and neurological issues.
Digestion and absorption of protein Dr.Ashok Kumar j
Proteins are digested in the stomach by pepsin and in the small intestine by proteases like trypsin, chymotrypsin, and carboxypeptidases secreted by the pancreas. These enzymes break proteins down into dipeptides and amino acids. Amino acids are absorbed into the bloodstream via active transport mechanisms in the intestinal epithelium and transported to tissues. Some diseases that can impair protein digestion and absorption include pancreatitis, inborn errors of amino acid transport, and celiac disease.
Gluconeogenesis
Gluconeogenesis is the process by which glucose is synthesized from non-carbohydrate precursors like lactate, glycerol, and certain amino acids. It occurs primarily in the liver and involves bypassing the three irreversible steps of glycolysis through different enzymes. Key enzymes in gluconeogenesis include pyruvate carboxylase and PEP carboxykinase which catalyze reactions to bypass pyruvate kinase. Gluconeogenesis and glycolysis share certain intermediate compounds but are not simple reversals of each other due to different enzymatic pathways. Regulation of these two processes helps determine whether glucose or glycogen will be synthesized or broken down depending on the body's energy needs.

The document summarizes fatty acid synthesis. It begins with acetyl-CoA being carboxylated to malonyl-CoA by acetyl-CoA carboxylase. Then, the fatty acid synthase complex catalyzes the repeating cycle of condensation, reduction, dehydration, and reduction to elongate the fatty acid chain by two carbons each cycle. This occurs until a 16-carbon palmitate is synthesized, which then leaves the complex. NADPH provides reducing equivalents for the reductions, while the acyl carrier protein carries the growing chain between active sites in the complex.

Fatty acid Biosynthesis
The document summarizes fatty acid biosynthesis. Fatty acids are synthesized predominantly in the liver, kidney, and adipose tissue through a three stage process. In the first stage, acetyl CoA and NADPH are produced in the mitochondria and transferred to the cytosol. In the second stage, malonyl CoA is formed from acetyl CoA. In the third stage, fatty acid synthase complex containing seven polypeptides catalyzes the reactions of fatty acid synthesis through condensation, carbonyl group reduction, dehydration, and double bond reduction to form fatty acids from acetyl CoA and malonyl CoA.
Lipid synthesis and transport
Lipids are organic compounds that contain fatty acids and glycerol. They are synthesized in the liver and adipose tissue from acetyl-CoA and malonyl-CoA through a repeated cycle of reactions catalyzed by the fatty acid synthase complex. Lipids are insoluble in water and must be transported through the body within lipoproteins such as chylomicrons, VLDL, LDL, and HDL. Chylomicrons transport dietary lipids from the intestine to tissues, while VLDL transports lipids from the liver to tissues and LDL transports cholesterol to tissues. HDL is responsible for reverse cholesterol transport from tissues back to the liver.

There are three systems for fatty acid synthesis: de novo synthesis in the cytoplasm, chain elongation in mitochondria, and chain elongation in microsomes. De novo synthesis occurs primarily in the liver and adipose tissues, starting from acetyl-CoA derived from glucose. This synthesis takes place in the cytoplasm and requires acetyl-CoA transport from mitochondria via citrate. The document then details the multi-step process of de novo fatty acid synthesis catalyzed by acetyl-CoA carboxylase and fatty acid synthase, and describes regulation of synthesis by products, hormones,
Metabolism of Lipids PT.pdf explanation for presentation
This document provides an overview of lipid metabolism. It discusses the classification of lipids and lipoprotein systems. The major pathways discussed include the oxidation and synthesis of fatty acids, metabolism of unsaturated fatty acids, metabolism of acylglycerols, degradation of phospholipids, and cholesterol synthesis. Key aspects of lipid metabolism covered are the beta-oxidation of fatty acids, biosynthesis of fatty acids from acetyl-CoA, and the role of the liver in producing ketone bodies from fatty acids.
Lipid metabolism
The document summarizes lipid digestion and absorption. It begins with lipid digestion starting in the stomach by lingual and gastric lipases. It then discusses emulsification of lipids in the small intestine by bile salts and pancreatic enzymes that degrade triglycerides, cholesterol esters, and phospholipids. Absorbed lipids are packaged into chylomicrons for transport to tissues.
Fatty Acid Synthesis
This document provides an overview of lipid biosynthesis and fatty acid synthesis. It discusses the key enzymes and cofactors involved, including acetyl-CoA carboxylase and fatty acid synthase. Fatty acid synthesis occurs in the cytoplasm through a repeating cycle of condensation, reduction, dehydration, and reduction reactions that results in the formation of palmitic acid from acetyl-CoA and malonyl-CoA. Regulation involves factors like substrate availability, acetyl-CoA carboxylase activity, and hormones like insulin and glucagon. The multi-enzyme fatty acid synthase complex enhances the efficiency of fatty acid synthesis.
DIGESTION, ABSORPTION AND METABOLISM OF LIPIDS.docx
This document provides information on the digestion, absorption, and metabolism of lipids. It discusses how dietary lipids are broken down by lipases in the mouth, stomach, and small intestine. Pancreatic lipase plays a major role in digesting triglycerides into fatty acids and monoacylglycerides. These products are absorbed via micelles in the small intestine and resynthesized into triglycerides for transport to the liver and peripheral tissues. The document also outlines the pathways of beta-oxidation of fatty acids in mitochondria, ketogenesis in the liver from fatty acids, and utilization of ketone bodies by extrahepatic tissues.

The document summarizes de novo fatty acid synthesis. It occurs in the liver, kidney, adipose tissue, and lactating mammary gland. Enzymes are located in the cytosol. Acetyl CoA from the mitochondria is the starting material and is converted to malonyl CoA by acetyl CoA carboxylase in an ATP-dependent reaction. Fatty acid synthase complex then catalyzes sequential reactions to produce palmitate through seven cycles. Production is regulated by enzymes, metabolites, hormones, and diet.
Fatty acid synthesis:- Everything you need to know
Fatty acid synthesis occurs through a repeated cycle of condensation, reduction, dehydration, and reduction reactions. Acetyl-CoA is carboxylated to malonyl-CoA by the enzyme acetyl-CoA carboxylase, providing the two-carbon building blocks. The fatty acid synthase complex catalyzes the cycle of reactions, with the growing fatty acid chain attached to an acyl carrier protein. Typically 16 cycles produce palmitate, which is then released from the complex. Key cofactors include NADPH, ATP, biotin, and bicarbonate. Fatty acid synthesis takes place in the cytoplasm of tissues like liver, adipose, and lactating mammary

Lipid metabolism is the processing of lipids for energy use, energy storage, and structural component (Cholesterol & lipoproteins) production. Lipids are digested by lipase enzymes in the GI tract (with the help of bile acids) and are absorbed directly through the cell membrane. Free fatty acids are then resynthesized into triacylglycerols (TAGs) in the enterocytes. Finally, lipid components are repackaged into chylomicrons and transported throughout the body for use or storage.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
