Chemical Information
FooDB Name4-Mercapto-4-methyl-2-pentanone
Description4-Mercapto-4-methylpentan-2-one, also known as 4-mercapto-4-methylpentan-2-one or 4-mercapto-4-methylpentan-2-one, belongs to the class of organic compounds known as ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. Thus, 4-mercapto-4-methylpentan-2-one is considered to be an oxygenated hydrocarbon lipid molecule. 4-Mercapto-4-methylpentan-2-one is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 4-Mercapto-4-methylpentan-2-one is a blackcurrant, box tree, and cat-urine. 4-Mercapto-4-methylpentan-2-one has been detected, but not quantified in, alcoholic beverages. This could make 4-mercapto-4-methylpentan-2-one a potential biomarker for the consumption of these foods.
