The Unique Properties of Gamma-Polyglutamic Acid
Gamma-Polyglutamic acid, or g-PGA, is a naturally occurring biopolymer composed of homo-polyamide units of D- and L-Glutamic acid. The polymer’s optically active nature and chiral center in every glutamate unit give it distinct properties, including high hygroscopicity. When in its free acid form, g-PGA is water-insoluble; however, the sodium salt form, as found in SAT-PGA-LW / HW, becomes water-soluble and readily utilized in different formulations.
