Glycine cas:56-40-6, also known as aminoacetic acid, is a white or pale yellow crystal that easily dissolves in water and has a sweet taste. It plays a crucial role in various bodily functions and is involved in the synthesis of proteins, DNA, and collagen.

Glycine is an amino acid that has a single hydrogen atom as its side chain. It is the simplest stable amino acid (carbamic acid is unstable), with the chemical formula NH2‐CH2‐COOH. Glycine is one of the proteinogenic amino acids. It is encoded by all the codons starting with GG (GGU, GGC, GGA, GGG).
