Product description

Polyglutamic Acid (γ-PGA) is a kind of polypeptide in which glutamate is polymerized via γ-amide linkages.

Originally discovered in the marine jellyfish, γ-PGA helps the jellyfish to store water in its fragile tissue and therefore it would not dehydrate in salty sea water.Today,Polyglutamic Acid can be gained from a beloved traditional Japanese food ‘natto’, the fermented soybeans. It can also be biosynthesed from L-glutamic acid using the microbe known as Bacillus subtilis.
