Metabolite Identification
Common Name3-Methyl-1-hydroxybutyl-ThPP
Description3-Methyl-1-hydroxybutyl-ThPP belongs to the class of organic compounds known as thiamine phosphates. These are thiamine derivatives in which the hydroxyl group of the ethanol moiety is substituted by a phosphate group. 3-Methyl-1-hydroxybutyl-ThPP is a very strong basic compound (based on its pKa). 3-Methyl-1-hydroxybutyl-ThPP exists in all living organisms, ranging from bacteria to humans. Within humans, 3-methyl-1-hydroxybutyl-THPP participates in a number of enzymatic reactions. In particular, 3-methyl-1-hydroxybutyl-THPP and lipoamide can be converted into S-(3-methylbutanoyl)-dihydrolipoamide-e through its interaction with the enzymes 2-oxoisovalerate dehydrogenase subunit beta, mitochondrial and 2-oxoisovalerate dehydrogenase subunit alpha, mitochondrial. In addition, 3-methyl-1-hydroxybutyl-THPP can be biosynthesized from ketoleucine and thiamine pyrophosphate; which is mediated by the enzyme 2-oxoisovalerate dehydrogenase. In humans, 3-methyl-1-hydroxybutyl-THPP is involved in the metabolic disorder called the 2-methyl-3-hydroxybutyryl-coa dehydrogenase deficiency pathway.
