General description
3-Hydroxybutyric acid forms films of random copolymer with (R)-3-hydroxypentanoic acid, (R)-3-hydroxyhexanoic acid, 4-hydroxybutyric acid, 6-hydroxyhexanoic acid and (S,S)-lactide by the melt-crystallized method. It is an important intermediate for the fine chemical industry.
Application
3-Hydroxybutyric acid was used in enantioselective synthesis of D-(-)-3-hydroxybutyric acid by Escherichia coli.

Wild-type bacteria including Escherichia coli normally do not produce extracellular D-(-)-3-hydroxybutyric acid (3HB). To produce extracellular chiral 3HB, a new pathway for synthesis of 3HB was constructed by simultaneous expression of genes of beta-ketothiolase (phbA), acetoacetyl-CoA reductase (phbB), phosphor-transbutyrylase (ptb)

In addition to plasma metabolites and hormones participating as humoral signals in the control of feed intake, oxidative metabolic processes in peripheral organs also generate signals to terminate feeding. Although the degree of oxidation over longer periods is relatively constant

Due to oil shortage and environmental problems, synthetic plastics have to be replaced by different biodegradable materials. A promising alternative could be polyhydroxyalkanoates (PHAs), and the low-cost abundant agricultural starchy by-products could be usefully converted into PHAs by properly selected
