Chemical Information
FooDB Name1,2-dihydroxy-5-(methylthio)pent-1-en-3-one
Description1,2-dihydroxy-3-keto-5-methylthiopentene, also known as acireductone or 1,2-dihydroxy-5-(methylsulfanyl)pent-1-en-3-one, is a member of the class of compounds known as alpha-branched alpha,beta-unsaturated ketones. Alpha-branched alpha,beta-unsaturated ketones are alpha,beta-unsaturated ketones that carry a branch on the alpha carbon. They have the generic structure RC(=O)C(R')=C, R = organyl group and R'= any heteroatom. 1,2-dihydroxy-3-keto-5-methylthiopentene is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 1,2-dihydroxy-3-keto-5-methylthiopentene can be found in a number of food items such as breakfast cereal, lettuce, rocket salad, and sea-buckthornberry, which makes 1,2-dihydroxy-3-keto-5-methylthiopentene a potential biomarker for the consumption of these food products. 1,2-dihydroxy-3-keto-5-methylthiopentene exists in all eukaryotes, ranging from yeast to humans.
