| NIST chemical information | Information provided by: webbook.nist.gov (external link) |
| overview | currently HMB is mainly produced by chemical methods, with low yield, high cost, many by-products and serious environmental pollution. In 1981, the Hasegawa reported that β-methylbutyric acid produced HMB. In 1997, the fermentation process of transforming MBA to produce HMB was preliminarily explored. Some work was done in the improvement of culture medium and the optimization of culture conditions, which improved the ability of the strain to transform MBA to produce HMB. |
| Uses | The calcium salt of β-hydroxy-β-methylbutyric acid (HMB) can be used as a functional feed additive to promote animal growth, reduce fat, increase lean meat, and ensure animal health; it can also be used as a health product for athletes to prevent muscle damage and muscle protein breakage during endurance training; it can also be used as an effective ingredient in weight loss foods, it has broad market prospects. |
| Biological activity | 2-Hydroxy-2-methylbutyric acid is an abnormal metabolite found in the urine of patients, usually found in the urine of patients with hydroxyglutaric aciduria and maple diabetes. Acid is also a secondary metabolite found in urine after exposure to gasoline additive TAME. |
