Introduction Storage proteins are a type of protein that acts as a reservoir of metal ions and amino acids, which can be combined and used for maintenance and growth. Proteins are classified according to their structure, origin, and function. Protein is a type of large organic molecule, consisting of a chain of one or more […]

Introduction Tertiary structure is the three-dimensional arrangement of all the atoms in a protein having different types of bonds. The disulfide bond is one of them, the secondary structure of the polypeptide chain is determined by the short-range structural relationship of amino acid residues. Whereas tertiary structure is conferred by long-range aspects of amino acid

Introduction Protein is a complex nitrogenous complex with a high molecular mass that is a polymer of amino acids. This macromolecule is considered to be the main component of all life. It is not possible to imagine the existence of any animal without protein. All proteins are composed of carbon, hydrogen, oxygen, and nitrogen. There

Introduction The Carboxyl group (-COOH) of one amino acid is attached to the amino group of another amino acid by a covalent bond called a peptide bond. When a peptide bond forms a water molecule is eliminated. Each amino acid unit in the peptide is known as the residue. All peptides have two ends, amino-terminal

Introduction Pentose sugar is a component of nucleotides. Nucleotides are biological molecules that act as monomers and as subunits of DNA and RNA. These biological molecules carry energy packets to the cell in the form of nucleoside triphosphate (ATP, GTP, CTP, and UTP), which play a key role in metabolic processes. Nucleotides are formed by

Introduction The body constantly needs energy to control various biological functions. The organism consumes food to gain this energy. The static energy in food that is stored from solar energy through the process of photosynthesis is converted into kinetic energy through a biochemical process of respiration. The organism performs physiological functions such as food intake,

Introduction Ribose 5-phosphate is a product produced in the non-oxidative phase of the pentose phosphate pathway. The sequence of steps of enzymatic reactions where a precursor is converted into a product through a series of metabolic intermediates is known as the metabolic pathway. The pentose phosphate pathway is also a metabolic pathway. It is the

Introduction The biogeochemical cycle is an important cycle in the biological world. As the name suggests biogeochemical cycles cannot be completed without living beings hence organisms are also deeply dependent on this cycle. The nitrogen cycle is one of the most important biogeochemical cycles of all the cycles. It is an essential element and it

Introduction Food serves as the primary source of nutrition for both animals and the human body. When consumed in solid, semi-solid, or liquid forms, it undergoes a series of digestive processes within the human body. This digestion is essential as it provides the body with the necessary energy for various physiological functions. The diverse organic

Introduction Anion exchange vs cation exchange is the two forms of ion-exchange chromatography. These are the two chemical methods used to separate molecules according to their net surface charge. There are some differences between these two chemical methods. An ion is an atom or molecule. When an atom is charged positively or negatively by accepting
