Common NameCapryloylglycine
DescriptionCapryloylglycine is an acylglycine consisting of caprylic acid (an 8-carbon medium chain fatty acid) conjugated to glycine. Acylglycines have an aliphatic acyl chain attached to the amino group of glycine through a peptide bond. Capryloylglycine is a solid with moderate solubility in water. Acylglycines are produced through the action of the enzyme glycine N-acyltransferase (EC Acylglycines are normally minor metabolites of fatty acids. However, the excretion of certain acylglycines is increased in several inborn errors of metabolism. In certain cases, the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation, including medium-chain acyl-coenzyme A (CoA) dehydrogenase (MCAD) deficiency and multiple acyl-CoA dehydrogenation defect (MAD) (PMID: 10708405 ). Capryloylglycine is frequently used as a cosmetic ingredient where it functions as a conditioning agent or a surfactant. It helps protect the skin’s surface from water loss and can enhance the effectiveness of cosmetic preservatives. Capryloylglycine-containing creams have been shown to inhibit hair growth in individuals suffering from hypertrichosis (PMID: 33934471 ), Due to it inhibiting ornithine decarboxylase 1, which is present in hair follicles.
