Description

Application

3-Hydroxyisobutyrate (HIBA) may be used to study the distribution, characterization and kinetics of enzymes involved in branched chain amino acid metabolism such as 3-hydroxyisobutyrate dehydrogenase (EC: 1.1.1.31) and 3-hydroxyisobutyryl-CoA hydrolase (EC: 3.1.2.4).

Biochem/physiol Actions

3-Hydroxyisobutyrate (HIBA), is formed in the valine catabolism[1], it is a reactant of enzyme 3-hydroxyisobutyrate dehydrogenase (EC: 1.1.1.31) and 3-hydroxyisobutyryl-CoA hydrolase (EC: 3.1.2.4); it was found to have increased concentrations in MS patient metabolic profiles[2].

Packaging
