Metabolite Identification
Common Name2-Methyl-1-hydroxybutyl-ThPP
Description2-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. 2-Methyl-1-hydroxybutyl-ThPP exists in all living organisms, ranging from bacteria to humans. 2-Methyl-1-hydroxybutyl-ThPP has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make 2-methyl-1-hydroxybutyl-THPP a potential biomarker for the consumption of these foods. 2-Methyl-1-hydroxybutyl-ThPP is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review very few articles have been published on 2-Methyl-1-hydroxybutyl-ThPP.
