Glycine (Gly, G) is a nonpolar amino acid. It is the simplest of the 20 standard (proteinogenic) amino acids: its side chain is a hydrogen atom. Because there is a second hydrogen atom at the α carbon, glycine is not optically active. Since glycine has such a small side chain, it can fit into many places where no other amino acid can. For example, only glycine can be the internal amino acid of a collagen helix. Glycine is very evolutionarily stable at certain positions of some proteins (for example, in cytochrome c, myoglobin, and hemoglobin), because mutations that change it to an amino acid with a larger side chain could break the protein's structure. Most proteins contain only small quantities of glycine. A notable exception is collagen, which is about one-third glycine.

Glycine is a hydrophilic amino acid with uncharged polar groups and is used in the biosynthesis of purines and porphyrins. Increased with nonketotic hyperglycinemia, arginosuccinic aciduria, carbamoyl phosphate synthetase deficiency, lysinuric protein intolerance, hyperprolinemia, iminoglycinuria, and ornithine transcarbamylase deficiency.
