應用

3-羟基异丁酸(HIBA)可用于研究参与支链氨基酸代谢的酶的分布、表征和动力学,例如,3-羟基异丁酸脱氢酶(EC:1.1.1.31)和3-羟基异丁酰辅酶A水解酶(EC:3.1.2.4)。(R)-β-羟基异丁酸酯可用于立体特异性研究。

生化/生理作用

3-hydroxyisobutyric aciduria is an organic aciduria with a poorly understood biochemical basis. It has previously been assumed that deficiency of 3-hydroxyisobutyrate dehydrogenase (HIBADH) in the valine catabolic pathway is the underlying enzyme defect, but more recent evidence makes it likely

Only a single patient with 3-hydroxyisobutyryl-CoA hydrolase deficiency has been described in the literature, and the molecular basis of this inborn error of valine catabolism has remained unknown until now. Here, we present a second patient with 3-hydroxyisobutyryl-CoA hydrolase deficiency

The branched-chain amino acids (BCAAs)--isoleucine, leucine, and valine--belong to the limited group of substances transported through the blood-brain barrier. One of the functions they are thought to have in brain is to serve as substrates for meeting parenchymal energy demands.

The chiral metabolites 3-hydroxyisobutyric acid (HIBA) and 3-aminoisobutyric acid (AIBA) are intermediates in the pathways of L-valine and thymine and play an important role in the diagnosis of the very rare inherited metabolic diseases 3-hydroxyisobutyric aciduria (McKusick 236975) and methylmalonic
