In vitro study The reduced activity of methylcrotonyl-CoA carboxylase (MCC) leads to an elevated excretion of 3-methylcrotonic acid, the product of its hydration (3-hydroxyisovaleric acid: 3-HIA), and 3-methylcrotonylglycine, formed by conjugation with glycine.
In vivo study In male mice (ICR/Jcl) at 8 weeks of age fed the biotin-deficient diet for 6 weeks, the concentration of urinary 3-Hydroxyisovaleric acid is 114.2 mM creatinine, which is higher than the concentration of 35.2 mM creatinine in mice fed the biotin-deficient diet for 4 weeks.

3-B-HYDROXYBUTYRIC ACID - Reference Information

Overview β-hydroxyisovalerate is also known as 3-hydroxy-3-methylbutanoic acid. 3-hydroxy-3-methylbutanoic acid (also known as "beta-hydroxy-beta-methylbutanoic acid", "3-hydroxyisovalerate", "HMB") it is a metabolic product of leucine in essential amino acids, which can reduce the damage of muscle tissue, increase muscle and muscle strength, improve the recovery ability of muscle tissue damage, improve the balance of muscle synthesis and decomposition, beneficial compounds that maintain muscle and muscle strength, reduce body fat, tighten, improve basal metabolism and other functions.
preparation add 47G (13.3 mol) of an aqueous solution of sodium hypochlorite at a concentration of wt% to the flask, cool, 20.0g(0.172mol) of diacetone alcohol was added while keeping it at 0 °c to 10 °c, and stirring was continued at 0 °c to 10 °c for 15 minutes to allow the diacetone alcohol to react with sodium hypochlorite. The reaction was then acidified (pH: 60.8) with hydrochloric acid 1.0g(0.600mol) and concentrated to a residual weight of 30% g (approximately of the weight before concentration), 3-hydroxy-3-methylbutyric acid (HMB) free acid was collected by extraction with ethyl acetate (45ml x 3 times), the mixture of the three extracts was concentrated to obtain 14.9g of the free acid of HMB (0.126mol in terms of HMB).
biological activity 3-Hydroxyisovaleric acid is a metabolite normally present in human urine.
