Pyroglutamic acid (also known as PCA, 5-oxoproline, pidolic acid, or pyroglutamate for its basic form) is an uncommon and little studied amino acid derivative in which the free amino group of glutamic acid or glutamine cyclizes to form a lactam. It is a metabolite in the glutathione cycle that is converted to glutamate by 5-oxoprolinase. Pyroglutamate is found in many proteins including bacteriorhodopsin. N-terminal glutamic acid and glutamine residues can spontaneously cyclize to become pyroglutamate.
This is one of several forms of blocked N-terminals which present a problem for N-terminal sequencing using Edman chemistry, which requires a free primary amino group not present in pyroglutamic acid. The enzyme pyroglutamate aminopeptidase can restore a free N-terminus by cleaving off the pyroglutamate residue.
FFunctionuction Of L-Pyroglutamic Acid
For food, medicine, cosmetics and other industries; organic synthesis intermediates, food additives: 
1.L-Pyroglutamic Acid is cardio protection; prevention of atherosclerosis 
2.L-Pyroglutamic Acid is cancer prevention 
3.L-Pyroglutamic Acid is prevention of tooth decay and gum disease 
4.L-Pyroglutamic Acid is kidney function improvement 
5.L-Pyroglutamic Acid anti-platelet aggregation to prevent blood clotting 
6.L-Pyroglutamic Acid is liver protection 
7.L-Pyroglutamic Acid is protection and restoration of immune system

Apaaplication Of L-Pyroglutamic Acid
1. The goods are broad-spectrum antimicrobial agents, many Rickettsia, Mycoplasma, Chlamydia, spirochetes, amoeba and some malaria parasites are also sensitive to the goods. Enterococcus is resistant to it. Other such as actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, Vibrio, Brucella, Campylobacter, Yersinia are sensitive to the product. 2.The goods on Neisseria gonorrhoeae and meningococcus have a certain antibacterial activity, but resistance to penicillin Neisseria gonorrhoeae is also resistant to oxytetracycline. Over the years due to the wide application of tetracyclines, clinical common pathogens resistant to oxytetracycline serious, including Staphylococcus aureus and other Gram-positive bacteria and most Gram-negative bacilli. There is cross-resistance between different varieties of tetracycline antibiotics. 3.The mechanism of action of the drug for the drug can specifically with the bacterial ribosome 30S subunit A site binding, inhibition of peptide chain growth and the impact of bacterial protein synthesis. 4.For dysentery, trachoma, conjunctivitis, pneumonia, otitis media, skin purulent infection. Also used for the treatment of amebic enteritis and intestinal infections.

1.Pharmaceutical intermediates, medical supplements.
2. Has a strong moisturizing capabilities, strong penetration in the skin. As a high-nutrient in nature, easily absorbing additives, the skin conditioning of Use, as a moisturizing agent
