Gluts transporters 
There are various conditions that are related glucose transporters. rach category treated differently and the side effects thus, varies. In this section, glucose 1 transporters and various condition related to it have been discussed.
Glucose receptors1
There are 13 glucose transporter proteins (GLUTs) that transport glucose across cell membranes. They are divided into 3 classes. Class I includes GLUT1-4, the most well studied of which are GLUT1, GLUT2, GLUT3 and GLUT4. GLUT1 transports glucose across the blood-brain barrier. GLUT2 acts as a bidirectional transporter in the liver and pancreas. GLUT3 transports glucose into neurons. GLUT4 is the insulin-regulated transporter that transports glucose into muscle and fat cells for storage. Defects in these transporters can lead to diseases like diabetes.
Presentation glucose transporters
Glucose is the main carbohydrate in blood, circulating at 65-110 mg/100 ml. It is an important fuel for muscles. Glucose enters muscles via GLUT4 glucose transporters. There are several glucose transporters with different properties - GLUT1 transports glucose in most cells, GLUT2 in liver and pancreas, GLUT3 in neurons and testes, and GLUT4 in muscles and fat which is activated by insulin. Insulin promotes glucose uptake in muscles by recruiting more GLUT4 transporters to the membrane from intracellular storage vesicles.
Glucose transport
Glucose transport into cells is mediated by glucose transporter (GLUT) proteins. [1] There are five main GLUT transporters that are involved in glucose transport and each has a distinct tissue distribution and function. [2] GLUT transporters use a flip-flop mechanism to transport glucose across the cell membrane according to the concentration gradient. [3] Insulin regulates glucose transport by stimulating the translocation of GLUT4 and GLUT1 transporters from intracellular vesicles to the cell membrane, increasing the influx of glucose into cells.
Glucose Transporters
Glucose transporters (GLUTs) facilitate the uptake of glucose in cells. The main GLUTs are GLUT1, GLUT2, GLUT3, GLUT4, and GLUT5. GLUT1 transports glucose in red blood cells and various tissues. GLUT2 has low affinity and transports glucose in the liver and pancreatic beta cells. GLUT3 transports glucose into brain cells with high affinity. GLUT4 mediates insulin-dependent glucose uptake in muscle and fat cells. GLUT5 transports fructose. SGluT cotransports glucose and sodium from the intestinal and renal lumens into cells.
Digestion and Absorption of Carbohydrates- Biochemistry
The document summarizes digestion and absorption of carbohydrates. Carbohydrates are broken down into monosaccharides like glucose in the mouth by saliva and in the small intestine by pancreatic enzymes. Glucose is then absorbed into the bloodstream through active transport using sodium-glucose transporters in the intestine or facilitative transport depending on concentration gradients across the intestinal wall. Different glucose transporters (GLUTs) are responsible for transporting glucose and other sugars into tissues throughout the body.
glucose metabolism insulin
This document summarizes the role of insulin in helping glucose enter cells. It discusses:
- Insulin is a hormone secreted by beta cells in the pancreas that helps glucose enter liver, fat, and muscle cells.
- When insulin binds to cell receptors, it causes conformational changes and signal transduction pathways that activate transporters to bring glucose transporters to the cell surface.
- The net effect is lowering blood glucose levels and increasing glycogen stores by stimulating pathways that uptake and process glucose while inhibiting gluconeogenesis and glycogen breakdown.

These hormones work together to regulate blood sugar levels. Diabetes occurs when there is a deficiency or absence of insulin from the beta cells, leading to high blood sugar. The two main types of diabetes are type 1 diabetes, which is usually diagnosed in childhood and is due to destruction of the beta cells, and type 2 diabetes, which accounts for 90% of cases and is
Pancreatic islet
The document discusses the pancreas and pancreatic islets. The pancreas is a large gland that secretes hormones and is part of both the endocrine and digestive systems. It contains clusters of cells called pancreatic islets (islets of Langerhans), the main cells of which are beta cells that secrete insulin, alpha cells that secrete glucagon, and delta cells that secrete somatostatin. These hormones work to regulate blood sugar levels. The pancreas is located in the abdomen behind the stomach and produces enzymes to aid in digestion.
The Endocrine Pancreas
The document discusses the endocrine pancreas and its role in regulating blood sugar levels. The endocrine pancreas contains clusters of cells called islets of Langerhans, which include alpha cells that produce glucagon, beta cells that produce insulin, and delta cells that produce somatostatin. Insulin lowers blood sugar by facilitating glucose uptake and storage, while glucagon raises blood sugar by promoting glucose release and production. Somatostatin inhibits the secretion of insulin and glucagon to regulate their levels.
Role of insulin in human body
Insulin is a polypeptide hormone composed of 51 amino acids that is responsible for several roles in the body. It binds to insulin receptors on target cells and activates a cascade of phosphorylation events. This leads to the biological effects of insulin, which include increasing glucose uptake by tissues, stimulating glycogen and lipid synthesis, and inhibiting gluconeogenesis and lipolysis. Insulin helps regulate blood glucose levels and the metabolism of carbohydrates, fats, and proteins.

Adipose tissue as an endocrine organ
This document summarizes the role of adipose tissue and the hormone leptin. It describes the structure of adipose tissue and its secretory products, including leptin. Leptin is produced primarily in white adipose tissue and plays a key role in regulating energy intake and expenditure. Leptin acts on the hypothalamus to reduce appetite and food intake through various neuronal pathways. However, obesity is associated with leptin resistance. The document also discusses the roles of leptin in puberty, bone homeostasis, the immune system, and other physiological systems.
Insulin, glucagon and diabetes mellitus
The pancreas secretes two important hormones, insulin and glucagon, which play crucial roles in regulating glucose, lipid, and protein metabolism. Insulin promotes the storage and use of glucose by stimulating its uptake into cells and its conversion to glycogen or fat. It also inhibits gluconeogenesis and fat breakdown. A lack of insulin has the opposite effects, increasing gluconeogenesis and fat breakdown for energy.
Pancreatic hormones
The document summarizes the functions of the pancreas and pancreatic hormones. The pancreas secretes digestive enzymes into the small intestine and regulates blood sugar levels by secreting the hormones insulin and glucagon. Insulin promotes glucose uptake and storage, while glucagon promotes glucose release from stores. A lack of insulin leads to diabetes mellitus, characterized by high blood sugar and metabolic dysregulation. The document provides details on the metabolic effects of insulin and glucagon on carbohydrate, fat, and protein metabolism.
Endocrine System
Hormones regulate many bodily functions through feedback mechanisms. Insulin and glucagon regulate blood glucose levels through negative feedback with the pancreas. When blood glucose levels rise, the pancreas secretes insulin to lower them. Leptin from fat cells signals satiety in the brain. Melatonin from the pineal gland controls circadian rhythms and its use can help with jet lag by resynchronizing the body clock. Thyroxine from the thyroid increases metabolism and helps control body temperature.

Carbohydrates provide the largest source of calories and include starch, lactose, and sucrose. The small intestine breaks down carbohydrates into monosaccharides like glucose through digestion by enzymes attached to the intestinal wall. These monosaccharides are then absorbed into the bloodstream and transported to tissues like muscle and liver to be used for energy or stored as glycogen for later use.
Carbohydrate.ppt
1. Carbohydrate digestion begins in the mouth and small intestine through enzymes like amylase and disaccharidases.
2. Further digestion by pancreatic enzymes occurs in the small intestine through enzymes like pancreatic amylase.
3. Final digestion is carried out by enzymes in the intestinal mucosal cells, breaking down sugars into monosaccharides that can be absorbed.
Uniporter catalyzed transport
Uniporter proteins transport molecules like amino acids and sugars across cell membranes. GLUT1 is a specific uniporter protein that transports glucose. It is encoded by the SLC2A1 gene and belongs to the major facilitator super family. GLUT1 is expressed in fetal tissues, erythrocytes, and the endothelial cells of the blood brain barrier where it regulates glucose uptake. It undergoes conformational changes to alternately expose its glucose binding site inside and outside the cell to transport glucose across the membrane. GLUT1 plays important roles in supplying glucose to the brain and developing fetus.
Monosachrides
This document discusses the absorption of monosaccharides in the small intestine. It notes that monosaccharides like glucose, fructose, and galactose are produced from carbohydrate digestion and absorbed in the duodenum and jejunum. Glucose accounts for 80% of absorbed monosaccharides. Glucose absorption involves sodium-glucose cotransporters, while fructose absorption occurs via facilitated diffusion. Factors like thyroid hormones and vitamins can influence absorption rates. Defects in monosaccharide transporters can cause conditions like glucose-galactose malabsorption.

The document outlines several major pathways involved in carbohydrate metabolism.
002 carbohydrate Metabolism 1.ppt
The document summarizes carbohydrate metabolism. It discusses the digestion, absorption, and utilization of carbohydrates. Carbohydrate digestion occurs via salivary and pancreatic amylases in the mouth and small intestine, breaking down starches and glycogen into disaccharides and trisaccharides that are then further broken down by intestinal enzymes. Absorption occurs mainly in the jejunum via both active and facilitated transport. Glucose is then distributed to tissues via the bloodstream and undergoes glycolysis and other pathways to produce energy or be used for biosynthesis. Glycolysis is discussed in detail, including its regulation by key enzymes and hormones.

Endocrine function of pancrease.peyudrurudrdf
The pancreas secretes two important hormones - insulin and glucagon. Insulin is produced by beta cells in the pancreas and regulates carbohydrate and fat metabolism. It causes cells to absorb glucose from the blood and store it as glycogen in the liver and muscles or as triglycerides in fat cells. Insulin is composed of two amino acid chains connected by disulfide bridges. It is synthesized as preproinsulin which is cleaved to form proinsulin and then insulin. Insulin secretion is increased by glucose, amino acids, and gastrointestinal hormones. Insulin promotes the storage and use of glucose, fatty acid synthesis and fat storage, and protein synthesis.

It describes the various sources of blood glucose, including dietary carbohydrates and the body's ability to produce glucose through glycogenolysis and gluconeogenesis when needed. Key hormones involved in regulating glucose include insulin, released after meals to lower blood glucose levels, and glucagon, released during fasting to raise blood glucose levels and promote glycogen breakdown and glucose production. Precise control of these opposing hormones is critical for metabolic health.

Digestion & absorption of carbohydrates
This document summarizes carbohydrate digestion in the human gastrointestinal tract. It describes how carbohydrates are broken down into smaller molecules by salivary and pancreatic amylases and intestinal disaccharidases and oligosaccharidases. The monosaccharides glucose, fructose and galactose that are produced are then absorbed into the bloodstream in the small intestine. Glucose absorption is an active process that utilizes sodium-glucose co-transporters, while fructose absorption occurs via facilitated diffusion. Factors that can influence carbohydrate absorption such as intestinal health, hormones and vitamins are also discussed.

PGx Analysis in VarSeq: A User’s Perspective
Since our release of the PGx capabilities in VarSeq, we’ve had a few months to gather some insights from various use cases. Some users approach PGx workflows by means of array genotyping or what seems to be a growing trend of adding the star allele calling to the existing NGS pipeline for whole genome data. Luckily, both approaches are supported with the VarSeq software platform. The genotyping method being used will also dictate what the scope of the tertiary analysis will be. For example, are your PGx reports a standalone pipeline or would your lab’s goal be to handle a dual-purpose workflow and report on PGx + Diagnostic findings.
The purpose of this webcast is to:
Discuss and demonstrate the approaches with array and NGS genotyping methods for star allele calling to prep for downstream analysis.
Following genotyping, explore alternative tertiary workflow concepts in VarSeq to handle PGx reporting.
Moreover, we will include insights users will need to consider when validating their PGx workflow for all possible star alleles and options you have for automating your PGx analysis for large number of samples. Please join us for a session dedicated to the application of star allele genotyping and subsequent PGx workflows in our VarSeq software.

biomechanics of running. Dr.dhwani.pptx
The biomechanics of running involves the study of the mechanical principles underlying running movements. It includes the analysis of the running gait cycle, which consists of the stance phase (foot contact to push-off) and the swing phase (foot lift-off to next contact). Key aspects include kinematics (joint angles and movements, stride length and frequency) and kinetics (forces involved in running, including ground reaction and muscle forces). Understanding these factors helps in improving running performance, optimizing technique, and preventing injuries.
