N6-Carboxymethyllysine (CML), also known as epsilon-(carboxymethyl)lysine, belongs to the class of organic compounds known as L-alpha-amino acids. These are alpha-amino acids which have the L-configuration of the alpha-carbon atom. CML is a Maillard reaction product, or dietary advanced glycation end-products (d-AGE), formed as a result of the thermal treatment of foods. Due to its chemical stability and its ubiquity in foods and in vivo, CML is used as a biomarker for the ingestion of thermally treated foods. CML is metabolized by intestinal bacteria under anaerobic conditions (PMID: 31091091).
