In this article we will discuss about the biosynthesis of various amino acids:- 1. Glutamic Acid Family 2. Aspartic Acid Family 3. α-Alanine, Serine, Glycine and Cysteine 4. Valine and leucine 5. Aromatic Amino Acids: Tyrosine, Phenylalanine, Tryptophan 6. Histidine. 1. Glutamic Acid Family: Glutamic acid is the main pathway for assimilation of ammonia by reductive amination of α-keto glutaric [...]
In this article we will discuss about Electron Transport System (ETS) in living organisms. Catabolism of energy-giving substrates (mostly glucose) up to the stage of pyruvic acid through EMP or EDP yields comparatively small amount of energy in the form of ATP by substrate-level phosphorylation. The anaerobic organisms have to be satisfied with this small amount of energy. But the [...]
In this notes we will discuss about:- 1. Nomenclature and Classification of Enzymes 2. Kinetics of Enzyme-Reactions 3. Enzyme Activity and Assay. Notes # Nomenclature and Classification of Enzymes: Before a scientific nomenclature of enzymes was developed, they were given trivial names, like pepsin, trypsin, rennin, ptyaline etc. Later, a more logical system of nomenclature was adopted by adding the [...]
