Metabolite Identification
Common Name(S)-2-Methyl-1-butanol
Description(S)-2-Methyl-1-butanol, also known as sec-butylcarbinol or 2-methyl butanol-1, belongs to the class of organic compounds known as primary alcohols. Primary alcohols are compounds comprising the primary alcohol functional group, with the general structure RCOH (R=alkyl, aryl). (S)-2-Methyl-1-butanol is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Thus, (S)-2-methyl-1-butanol is considered to be a fatty alcohol lipid molecule. (S)-2-Methyl-1-butanol exists in all eukaryotes, ranging from yeast to humans. (S)-2-Methyl-1-butanol is a malt tasting compound. (S)-2-Methyl-1-butanol is found, on average, in the highest concentration within milk (cow) and it has also been detected, but not quantified, in several different foods, such as red raspberries, nectarines, carobs, wild leeks, and black-eyed pea. This could make (S)-2-methyl-1-butanol a potential biomarker for the consumption of these foods.
