International Journal of Biochemistry and Biomolecules
the main aim of this journal is to create awareness in the scientific community and to provide a platform for discussion in the field of biochemistry and biomolecules. Precisely, journal deals with recent advancement in protein folding, purification, bio-separation and other related fields of biochemistry.
Cell biology is the study of cell structure and function, and it revolves around the concept that the cell is the fundamental unit of life. Focusing on the cell permits a detailed understanding of the tissues and organisms that cells compose.
the branch of science concerned with the chemical and physico-chemical processes and substances that occur within living organisms.
the processes and substances with which the science of biochemistry is concerned.
Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms.[1] Biochemical processes give rise to the complexity of life.
What is biochemistry?
Biochemistry explores chemical processes related to living organisms. It is a laboratory-based science combining biology and chemistry.
Biochemists study the structure, composition, and chemical reactions of substances in living systems and, in turn, their functions and ways to control them. Biochemistry emerged as a separate discipline when scientists combined biology with organic, inorganic, and physical chemistry. They began to study areas such as:
How living things get energy from food
The chemical basis of heredity
What fundamental changes occur in disease
Biochemistry includes the sciences of molecular biology, immunochemistry, and neurochemistry, as well as bioinorganic, bioorganic, and biophysical chemistry.
What do biochemists do?
Biochemists interact with scientists from a wide variety of other disciplines, usually on problems that are a very small piece of a very large and complex system.
Biochemists in industry are interested in specific applications that will lead to marketable products
Biochemists in academia or government labs conduct more basic and less applied research
Where is biochemistry used?
Biochemistry has obvious applications in medicine, dentistry, and veterinary medicine. Other applications include:
Food Science
Biochemists determine the chemical composition of foods, research ways to develop abundant and inexpensive sources of nutritious foods, develop methods to extract nutrients from waste products, and/or invent ways to prolong the shelf life of food products.
Agriculture
Biochemists study the interaction of herbicides/insecticides with plants and pests. They examine the structure–activity relationships of compounds, determine their ability to inhibit growth, and evaluate the toxicological effects on surrounding life.
Pharmacology, Physiology, Microbiology, Toxicology, and Clinical Chemistry
Biochemists investigate the mechanisms of drug actions; engage in viral research; conduct research pertaining to organ function; or use chemical concepts, procedures, and techniques to study the diagnosis and therapy of disease and the assessment of health.
The science concerned with the materials and various processes of life related to chemical basis of life.
The science concerned with the various molecules that occur in living cells and organisms and with their chemical reaction
the branch of science concerned with the chemical and physico-chemical processes and substances that occur within living organisms.
the processes and substances with which the science of biochemistry is concerned.
Biochemistry is the study of the chemical substances and vital processes occurring in living organisms. Biochemists focus heavily on the role, function, and structure of biomolecules. The study of the chemistry behind biological processes and the synthesis of biologically active molecules are examples of biochemistry.
Nitrogen assimilation is the formation of organic nitrogen
compounds like amino acids from inorganic nitrogen
compounds present in the environment. Organisms like
plants, fungi and certain bacteria that cannot fix nitrogen
gas (N2) depend on the ability to assimilate nitrate or
ammonia for their needs. Other organisms, like animals,
depend entirely on organic nitrogen from their food.
Gel electrophoresis is a method for separation and analysis
of macromolecules (DNA, RNA and proteins) and
their fragments, based on their size and charge.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Editor's Notes
FIGURE 1-3
The simplest form of life, usually without organelles. But, bacteria do compartmentalize their cytoplasm.
The bacteria here are really the Gram negative and positive bacteria. Cyanobacteria are in the Gram negative bacteria. The authors of your text should replace “Archaebacteria” with “Archaea” which are a completely different domain from Bacteria and Ekarya. Archaea have different ribosomes, membrane lipids and lack peptidoglycan but are still Prokaryotic.
Lots of compartments. When we cover metabolism we will find each biochemical pathway in different membrane bound compartments.
FIGURE 1–9a The three types of cytoskeletal filaments: actin filaments, microtubules, and intermediate filaments. Cellular structures can be labeled with an antibody (that recognizes a characteristic protein) covalently attached to a fluorescent compound. The stained structures are visible when the cell is viewed with a fluorescence microscope. (a) Endothelial cells from the bovine pulmonary artery. Bundles of actin filaments called “stress fibers” are stained red; microtubules, radiating from the cell center, are stained green; and chromosomes (in the nucleus) are stained blue.
FIGURE 1-10 The organic compounds from which most cellular materials are constructed: the ABCs of biochemistry. Shown here are (a) six of the 20 amino acids from which all proteins are built (the side chains are shaded pink); (b) the five nitrogenous bases, two five-carbon sugars, and phosphate ion from which all nucleic acids are built; (c) five components of membrane lipids; and (d) D-glucose, the simple sugar from which most carbohydrates are derived. Note that phosphate is a component of both nucleic acids and membrane lipids.
The BLACK ARROW !
Biochemistry is all about the Bulk elements for most biological polymers and major inorganic, physiological salts. enzyme cofactors will added as the trace elements.
Versatility of carbon bonding.
Carbon can form covalent single, double, and triple bonds (all bonds in red), particularly with other carbon atoms. Triple bonds are rare in biomolecules.
It is not important to know individual bond strengths, but rather to know ranges.
Single bonds are 200 to 450 kJ/mole, double bonds are 500-700 kJ/mole and triple bonds are ~900 kJ/mole (hardest to make or break).
Single bonds are rotatable, double bonds not so.
FIGURE 1–14 Geometry of carbon bonding. (a) Carbon atoms have a characteristic tetrahedral arrangement of their four single bonds.
(b) Carbon–carbon single bonds have freedom of rotation, as shown for the compound ethane (CH3—CH3). (c) Double bonds are shorter
and do not allow free rotation. The two doubly bonded carbons and the atoms designated A, B, X, and Y all lie in the same rigid plane.
Figure 1-16 Some common functional groups of biomolecules. Functional groups are screened with a color typically used to represent the element that characterizes the group: gray for C, red for O, blue for N, yellow for S, and orange for P. In this figure and throughout the book, we use R to represent “any substituent.” It may be as simple as a hydrogen atom, but typically it is a carbon-containing group. When two or more substituents are shown in a molecule, we designate them R1, R2, and so forth.
FIGURE 1–17 Several common functional groups in a single biomolecule. Acetyl-coenzyme A (often abbreviated as acetyl-CoA) is a carrier of acetyl groups in some enzymatic reactions. The functional groups are screened in the structural formula. As we will see in Chapter 2, several of these functional groups can exist in protonated or unprotonated forms, depending on the pH. In the space-filling model, N is blue, C is black, P is orange, O is red, and H is white. The yellow atom at the left is the sulfur of the critical thioester bond between the acetyl moiety and coenzyme A.

(c) Space-filling model, in which each atom is shown with its correct relative van der Waals radius.
Isomers such as maleic acid (maleate at pH 7) and fumaric acid (fumarate) cannot be interconverted without breaking covalent bonds, which requires the input of much more energy than the average kinetic energy of molecules at physiological temperatures.

Pasteur’s doctoral thesis established optical rotation of compounds having the same empirical chemistry other than crystal shape and optical properties.
Review
FIGURE 1–23 Complementary fit between a macromolecule and a small molecule. A glucose molecule fits into a pocket on the surface of the enzyme hexokinase (PDB ID 3B8A), and is held in this orientation by several noncovalent interactions between the protein and the sugar. This representation of the hexokinase molecule is produced with software that can calculate the shape of the outer surface of a macromolecule, defined either by the van der Waals radii of all the atoms in the molecule or by the “solvent exclusion volume,” the volume a water molecule cannot penetrate.
This is why colas sweetened with aspartame have a limited shelf life.

Some of thermodynamics is just adding and subtracting.
This is the best one from the text, but not Chapter 1. It fails to show the need of anabolism for UTP, GTP and CTP.

Review
FIGURE 1–33 Gene duplication and mutation: one path to generate new enzymatic activities. In this example, the single hexokinase gene in a hypothetical organism might occasionally, by accident, be copied twice during DNA replication, such that the organism has two full copies of the gene, one of which is superfluous. Over many generations, as the DNA with two hexokinase genes is repeatedly duplicated, rare mistakes occur, leading to changes in the nucleotide sequence of the superfluous gene and thus of the protein that it encodes. In a few very rare cases, the altered protein produced from this mutant gene can bind a new substrate—galactose in our hypothetical case. The cell containing the mutant gene has acquired a new capability (metabolism of galactose), which may allow it to survive in an ecological niche that provides galactose but not glucose. If no gene duplication precedes mutation, the original function of the gene product is lost.
