As a water-soluble aliphatic polyester, polyglutamic acid molecules have a large number of free hydrophilic carboxyl groups, so polyglutamic acid is highly water-soluble, biocompatible, biodegradable, and bioabsorbable.
Polyglutamic acid is non-toxic, non-immunogenic and chemically derivatizable. Polyglutamic acid can be degraded into small molecule glutamic acid spontaneously or under the promotion of enzymes in acidic aqueous solutions (such as gastric acid environment), and glutamic acid monomers can participate in The tricarboxylic acid cycle is absorbed by the human body without any toxic or side effects.
After Polyglutamic acid is decomposed or burned, the final products are carbon dioxide and water, which can be absorbed by plants and are non-toxic and harmless to the environment.
