Glycine (Gly), also known as glycine, is a non-essential amino acid with the formula C2H5NO2. Glycine is a constituent amino acid of the endogenous antioxidant reduced glutathione, which is often supplemented exogenously during severe stress in the body, and is sometimes called a semi-essential amino acid. [1] Glycine is one of the simplest amino acids. [4]Solid glycine is a white to off-white crystalline powder, odorless, non-toxic [2]. Soluble in water and almost insoluble in ethanol or ether.
