Glycine is one of the 20 amino acids.  It's three letter code is Gly, and it's single letter code is G. It is the simplest amino acid, with a hydrogen atom as a side chain - this means glycine is the only amino acid which does not have a chiral carbon atom [1].

Glycine has a function outside of the cell. It is a neurotransmitter at nerve cells. Its function lies at chemical synapses where its role as a neurotransmitter is to allow rapid signalling from cell to cell [2].

Glycine has two hydrogens attatched to the alpha carbon and is found in flexible areas of proteins due to its short side chain.
