Metabolite Identification
Common NamePyroglutamine
DescriptionPyroglutamine (CAS: 2353-44-8), also known as alpha-aminoglutarimide or 3-amino-1,6-dioxopiperidine, belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. Pyroglutamine is considered to be soluble (in water) and acidic. Pyroglutamine has been identified in the human placenta (PMID: 32033212 ).
