L-Pyroglutamic acid

Description:

L-Pyroglutamic acid, also known as 5-oxoproline, is a cyclic derivative of the amino acid glutamic acid. It is characterized by its five-membered lactam structure, which includes a carbonyl group and an amine group, contributing to its unique properties. This compound is a non-proteinogenic amino acid and plays a role in various biochemical processes, including the synthesis of glutathione, an important antioxidant in the body. L-Pyroglutamic acid is typically a white crystalline solid that is soluble in water and exhibits a slightly acidic nature due to the presence of the carboxylic acid group. It is often used in the pharmaceutical and cosmetic industries, as well as in nutritional supplements, due to its potential benefits in cognitive function and metabolic processes. Additionally, it has been studied for its role in cellular signaling and as a precursor in the synthesis of other biologically relevant compounds. Its CAS number, 98-79-3, is used for identification in chemical databases and regulatory contexts.

(S)-(-)-2-Pyrrolidone-5-carboxylic acid

CAS: 98-79-3

A hydrophilic and hygroscopic element of natural moisturizing factor (NMF) that maintains hydration of the skin stratum corneum.  Elevated levels of pyroglutamic acid in the blood, urine and brain lead to metabolic acidosis. Enhances blood circulation in the brain. Conjugation of pyroglutamic acid with Apaf-1 inhibitor peptoid 1, as a polymeric carrier, improves anti-apoptotic activity.
