1. Alanine

   Alanine (symbol Ala or A), or α-alanine, is an α-amino acid that is used in the biosynthesis of proteins. It contains an amine group and a carboxylic acid group, both attached to the central carbon atom which also carries a methyl group side chain. Consequently, its IUPAC systematic name is 2-aminopropanoic acid, and it is classified as a nonpolar, aliphatic α-amino acid. Under biological conditions, it exists in its zwitterionic form with its amine group protonated (as −NH3+) and its carboxyl group deprotonated (as −CO2−). It is non-essential to humans as it can be synthesised metabolically and does not need to be present in the diet. It is encoded by all codons starting with GC (GCU, GCC, GCA, and GCG). The L-isomer of alanine (left-handed) is the one that is incorporated into proteins. L-alanine is second only to leucine in rate of occurrence, accounting for 7.8% of the primary structure in a sample of 1,150 proteins. The right-handed form, D-alanine, occurs in polypeptides in some bacterial cell walls: 131  and in some peptide antibiotics, and occurs in the tissues of many crustaceans and molluscs as an osmolyte.

1. alanine

   Alanine is a non-essential amino acid that is used in the biosynthesis of proteins. It contains an amino group (-NH2), a carboxyl group (-COOH), and a side chain methyl group (-CH3), making it one of the simplest amino acids in terms of molecular structure. It can be synthesized in the body from pyruvate and branched chain amino acids, and it plays a key role in glucose metabolism and immune system function.
