In this article we will discuss about the molecular structure of proteins with the help of diagrams. Quantitatively, proteins are the chief organic components of most living organisms, as also of viruses. About 50% of the dry weight of bacterial cells is protein. The flagella, pili and fimbriae are made up entirely of proteins, and the cell membrane, cytoplasm, ribosomes [...]
In this article we will discuss about the biosynthesis of fatty acids and triglycerides. The Neutral simple lipids are esters of glycerol and long chain fatty acids containing generally 16 or 18 carbon atoms. The fatty acids may be saturated, like palmitic acid and stearic acid, or may be unsaturated, like oleic acid. Fatty acids are synthesized by step-wise addition [...]
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 [...]
