Description and Uses
Glycine (abbreviated as Gly or G) is an organic compound with the formula NH2CH2COOH. Having a hydrogen substituent as its side-chain, glycine is the smallest of the 20 amino acids commonly found in proteins. Its codons are GGU, GGC, GGA, GGG of the genetic code.
Glycine is a colourless, sweet-tasting crystalline solid. It is unique among the proteinogenic amino acids in that it is not chiral. It can fit into hydrophilic or hydrophobic environments, due to its minimal side chain of only one hydrogen atom. Glycine is also the genus name of the Soybean plant (species name = Glycine max).
Glycine is a nonessential amino acid that functions as a nutrient and dietary supplement. it has a solubility of 1 g in 4 ml of water and is abundant in collagen. it is used to mask the bitter aftertaste of sac- charin, for example, in artificially sweetened soft drinks. it retards rancidity in fat.
