1 R httpwwwcalbiochemcom Amino Acid and Peptide Nomenclature SystemThe symbol chosen for a given amino acid is derived from its trivial name and is usually the first three letters of this name. Peptide Bond. Amino acid residues in peptides and proteins are linked together through a covalent bond called the peptide bond.. Two amino acid molecules can be covalently joined through a substituted amide linkage, termed a . B.2. Properties of 2-amino acids . (B.2.2). Zwitterion. (dipolar) . amino acids contain both acidic and basic groups in the same molecule . therefore, are . amphoteric. in nature (capable of behaving as acids or bases). Collagen. Most abundant insoluble fibrous protein in the connective tissue of mammals. Makes up to 25%-35% of the whole body protein content . It comes from the Greek work “. kolla. ” which means glue. It is also called glue-producer. . . . Raja Ram Mohan Roy has come to be called the maker of modern India. What was good and noble in the past, he laid the foundations for a great future. He put an end to the horrible custom of burning the living wife with the dead husband. He was a great scholar and an independent thinker. He advocated the study of English, science, western medicine and technology. He spend his money on college to promote these studies.

All amino acids except glycine possess optical isomers due to the presence of asymmentric carbon atom. Some amino acids have a second assymmentric carbon e.g. isoleucine, threonine.. Each amino acid (aa) shares a common structure; i.e. an amine (NH. 2. ) group, an acid group (COOH), and a central carbon atom bonded to hydrogen and to a side chain (R).. The side chains qualify aas as acidic, basic, neutral, aromatic, and sulphur-containing amino acids..  . Amino . Acids are the building units of proteins. There are about 300 amino acids occur in nature. Only 20 of them enter in proteins synthesis..  . Structure of amino acids:. Four different . groups . A. .
