Metabolite Identification
Common NameIsopentanol
DescriptionIsoamylol, also known as isoamyl alcohol or 3-methylbutanol, 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). Thus, isoamylol is considered to be a fatty alcohol lipid molecule. Isoamylol exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Isoamylol exists in all eukaryotes, ranging from yeast to humans. Isoamylol has been found to be associated with the diseases known as ulcerative colitis; also isoamylol has been linked to the inborn metabolic disorders including celiac disease.
