Polyhydroxyalkanoates (PHA) are intracellular polyesters synthesized by many bacteria. In organisms, they primarily function as carbon and energy storage substances. They possess physicochemical properties similar to synthetic plastics, but also exhibit many superior properties not found in synthetic plastics, such as biodegradability, biocompatibility, optical activity, piezoelectricity, and gas barrier properties. PHAs show broad application prospects in biodegradable packaging materials, tissue engineering materials, sustained-release materials, electrical materials, and medical materials.

Function
PHA (polyhydroxy fatty acid ester) is a natural polymer widely found in microbial cells. High molecular weight materials made from this substance can be completely degraded into harmless components under both aerobic and anaerobic conditions.
PHA plays an increasingly important role in drug sustained-release systems due to its excellent biodegradability and biocompatibility.
