Amino acid glycine in human body

The proteins coded for by an allele are also molecules that consist of chains of smaller molecules. The subunits of protein are celled amino acids.

The collagen of skin, bone and connective tissue needs to be tough and stretchy, so it has repetitive structure that utilizes the amino acids glycine and hydroxylproline.

Glycine is a simple amino acid and is utilized by the liver to detoxify certain components of foods, such as benzoic acid.

It may also be involved in the synthesis of several body components, such as bile acids. Glutamic acid may act as a source material for the synthesis of other amino acids.

Glycine is a non-chiral molecule. Glycine can also be obtained from different sources such as the diet, protein breakdown, or synthesis from different precursors such as i-serine, glyoxylate, sarcosine, or from condensation of CO2, NH3, and 5,10-MTHF.

Glycine may also be manufactures from threonine through a metabolic process called degradation.

Glycine is a precursor of proteins, porphyrins, bile acids, and creatine; it acts as a neurotransmitter and a conjugating substance that aids the excretion of xenobiotics by making them more water-soluble.
