Poly glutamic acid, also known as gamma poly glutamic acid, natto glue, polyglutamic acid and so on, is L - glutamic acid, D - glutamic acid by gamma - amide formed by the combination of an amino acid polymer, polymer health unique three-dimensional structure of different molecular weight of poly glutamic acid to cooperate with each other, form the effect of multiple lock water, at the same time also has a certain effect of whitening, sunscreen, anti-wrinkle, etc.

Poly glutamic acid contains a lot of amide bond and free carboxyl, unique molecular structure to its good biocompatibility, biodegradable, security, stability, and water imbibition, with good performance, poly glutamic acid in biodegradable plastics, medicine, environment governance, sewage treatment, has been widely applied fertilizer, cosmetics and other fields.
