# Glycine

Glycine (three-letter code Gly, one-letter code G) is the simplest amino acid, with a single hydrogen atom as its side chain, making it the only achiral standard amino acid. Its small size gives peptide chains local flexibility, and glycine is common in turns and linker regions of synthetic peptides.
