Glycine is one of 20 amino acids commonly found in proteins. It has the chemical structure of acetic acid (vinegar) with one hydrogen atom replaced by an amino (NH2) group. Glycine is medically and biologically of great interest, whether it occurs by itself, in modified form (such as dimethyl glycine), or as part of a sequence of amino acids in proteins (for instance, creatinine).
Glycine is important in diverse fields including the study of liver metabolic processes, the development of sports supplements, and in childhood autism. Glycine serves as a neurotransmitter and has even been found in the far reaches of space. Learn more with informative articles by Bright Hub contributors.
