Polyglutamic acid (PGA) is a polymer of the amino acid glutamic acid (GA). Gamma PGA (Poly-γ-glutamic acid, γ-PGA) - the form where the peptide bonds are between the amino group of GA and the carboxyl group at the end of the GA side chain) - is a major constituent of the Japanese food natto. Gamma PGA is formed by bacterial fermentation.
Gamma PGA has a wide number of potential uses ranging from food and medicine to water treatment. It is widely being used as a drug delivery system in cancer treatment[1] and research is underway for its application in a treatment of type I diabetes and its potential use in the production of an AIDS vaccine.
