L-Pyroglutamic acid (Cat No.: R041849), also known as 5-oxoproline, is a naturally occurring cyclic derivative of the amino acid L-glutamic acid. It features a lactam ring formed by intramolecular cyclization of the amino and carboxyl groups. This compound plays a role in the γ-glutamyl cycle, involved in glutathione metabolism. It is used in biochemical research, particularly in studies of amino acid metabolism and neurochemistry. L-Pyroglutamic acid is also found in some protein N-termini. For research and laboratory use under controlled conditions.
