Metabolite Identification
Common NamePyroglutamic acid
DescriptionPyroglutamic acid, also known as pyroglutamate or pidolate, magnesium, 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. Pyroglutamic acid is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Pyroglutamic acid exists in all living species, ranging from bacteria to humans. Pyroglutamic acid is a potentially toxic compound.
