L-Pyroglutamic Acid (Highly Pure) by Molecular Depot is a L-pyroglutamic acid, the cyclic lactam of glutamic acid, described as a metabolite produced by Saccharomyces cerevisiae. Pyroglutamate forms the blocked N-terminus of some peptides and is an intermediate of the gamma-glutamyl cycle. It is used as a standard in metabolite analysis, as a building block in peptide chemistry and in glutathione cycle research. Each unit contains 100 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
