The body synthesizes glycine from another amino acid, serine. Its abbreviated form is Gly.

Glycine is the smallest amino acid known, consisting of only two carbon atoms. It is the most abundant component of collagen structure, formed by 30% of glycine, 20% of proline and hydroxyproline, and 10% of lysine and hydroxylysine.
