Application

β-Hydroxyisovaleric acid can be used as as a precursor for steroid alcohols.
It is widely used in the synthesis of the anthrax tetrasaccharide and its analogs as anthrax vaccine candidates.[1][2] β-hydroxyisovaleric acid can also be used in the synthesis of β-lactones by intramolecular dehydration condensation using 2-methyl-6-nitrobenzoic anhydride (MNBA).[3]

We report the clinical course and biochemical findings of a 10-year-old, mentally retarded girl with late-onset holocarboxylase synthetase (HCS, gene symbol HLCS) deficiency and only partial response to biotin. On treatment, even with an unusually high dose of 200mg/day, activities

Beta-hydroxy-beta-methylbutyrate (HMB) is a metabolite derived from leucine. The anti-catabolic effect of HMB is well documented but its effect upon skeletal muscle strength and fatigue is still uncertain. In the present study, male Wistar rats were supplemented with HMB (320

The use of ergogenic nutritional supplements is becoming inseparable from competitive sports. β-Hydroxy-β-Methylbutyric acid (HMB) has recently been suggested to promote fat-free mass (FFM) and strength gains during resistance training in adults. In this prospective randomized, double-blind, placebo-controlled study, we
