CAS: 25513-46-6 y-Polyglutamic Acid
PGA is a water soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation.
PGA is a sticky material first found in "natto", a fermented soybean.
PGA is an unusual anionic, naturally occurring homo polyamide that is made of D & L glutamic acid units connected by amide linkages between alpha amino & gamm carboxylic acid groups.
Gamm-poly-glutamic acid (gamm-PGA) is a natural occurring, multi-functional, and biodegradable biopolymer. It is produced through fermentation by Bacillus subtilis using glutamic acid. PGA is consists of glutamic acid monomers crosslinked between α-amino and y-carboxyl groups, and the molecular weight of PGA is usually between 100~1000 kDa. It is water-soluble, edible and non-toxictowards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.
