Description

General description

(R)-3-Hydroxybutyric acid, a monomer of the polymer polyhydroxybutyrate (PHB), is widely used as a nutrition source and a precursor for vitamins, antibiotics and pheromones. Its potential as a protective agent against neuronal death is investigated.

Application

2(R)-3-Hydroxybutyric acid may be used as an analytical reference standard for the quantification of the analyte in urine samples using achiral dual-capillary column gas chromatography. It may also be used as a standard in the production of enantiopure (R)-3-HB using non-conventional yeast A. adeninivorans as a production host and glucose as a carbon source. The purity is determined using gas chromatography-mass spectrometric analysis (GC-MS).
