Metabolite Identification
Common Name4-Methylumbelliferyl acetate
Description4-Methylumbelliferyl acetate, also known as 4-methyl-7-acetyloxy coumarin or 7-acetoxy-4-methylchromen-2-one, belongs to the class of organic compounds known as coumarins and derivatives. These are polycyclic aromatic compounds containing a 1-benzopyran moiety with a ketone group at the C2 carbon atom (1-benzopyran-2-one). 4-Methylumbelliferyl acetate has been detected, but not quantified in, a few different foods, such as fenugreeks (Trigonella foenum-graecum), green vegetables, and herbs and spices. This could make 4-methylumbelliferyl acetate a potential biomarker for the consumption of these foods. 4-Methylumbelliferyl acetate is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review very few articles have been published on 4-Methylumbelliferyl acetate.

Enzymes

General function:
Lipid transport and metabolism
Specific function:
Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. Hydrolyzes aromatic and aliphatic esters, but has no catalytic activity toward amides or a fatty acyl-CoA ester. Hydrolyzes the methyl ester group of cocaine to form benzoylecgonine. Catalyzes the transesterification of cocaine to form cocaethylene. Displays fatty acid ethyl ester synthase activity, catalyzing the ethyl esterification of oleic acid to ethyloleate.
