Polyglutamic acid (γ-PGA), also known as natto gum and polyglutamic acid, is a water-soluble, biodegradable, non-toxic, biopolymer prepared by microbial fermentation. γ-PGA polyglutamic acid is a sticky substance, which was first discovered in "Natto"-fermented beans. γ-PGA polyglutamic acid is a special anionic natural polymer, which is composed of α-amino group (α-amino) and γ-carboxyl group (γ-caboxyl) through amide linkage. The molecular weight of homo-polyamide γ-PGA ranges from 50,000 to 2 million Daltons.
poly-γ-glutamic acid, PGA for short，is a water-soluble polyamino acid produced by microbial fermentation in nature. Its structure is that glutamic acid unit passes through α-amino and γ -A high molecular polymer in which carboxyl groups form peptide bonds.
The characteristic of PGA:
Non-toxic to the human body and the environment, biodegradable, eco-friendly ·
Water-soluble, odorless, clean and transparent solution can be obtained ·
Easy to crosslink and form a hydrogel with excellent performance in the later stage ·
Can be made into sodium, calcium, magnesium, hydrogen type.
