Glycine 75.07 D R [1]

Glycine is the organic compound with the formula HO2CCH2NH2. It is one of the 20 amino acids commonly found in animal proteins. Its three letter code is gly, its one letter code is G, and its codons are GGU, GGC, GGA and GGG. Because of its structural simplicity, this compact amino acid tends to be evolutionarily conserved in, for example, cytochrome c, myoglobin, and hemoglobin. Glycine is the unique amino acid that is not optically active. Most proteins contain only small quantities of glycine. A notable exception is collagen, which contains about one-third glycine.

Glycine is manufactured industrially: treatment of chloroacetic acid with ammonia leads to the product in one step:
