Polyglutamic acid

1. Production introduction

　　Polyglutamic acid is a water-soluble polymeric amino acid produced by microbial fermentation in nature, and its structure is a polymer in which the glutamic acid unit forms a peptide bond through the α-amino group and the γ-carboxy group. Polyglutamic acid is a non-toxic, environmentally and human friendly polypolymer and is one of the typical representatives of biopolymers with the most active research. It can be synthesized in living organisms, but also has biocompatibility, biodegradability, biosafety, and can be consumed, thus it is widely used in many fields, such as medicine, industry, life, and environment.
