Glycine is a non-essential amino acid and has one of the simplest structure of all amino acids, allowing it to fit easily within protein chains and make space for structurally larger amino acids. This feature makes it very important for specific bodily functions. Glycine is also a precursor of creatine, which is used to construct DNA and RNA.
