描述
(e)-1-propene-1-sulfenic acid, also known as trans 1-propenylsulfenate, is a member of the class of compounds known as sulfenyl compounds. Sulfenyl compounds are organosulfur compounds a sulfenyl group with the general formula RS (R = organyl) (e)-1-propene-1-sulfenic acid is soluble (in water) and a very weakly acidic compound (based on its pKa). (e)-1-propene-1-sulfenic acid can be found in garden onion and onion-family vegetables, which makes (e)-1-propene-1-sulfenic acid a potential biomarker for the consumption of these food products.
