Metabolite Identification
Common Name2-Propene-1-thiol
Description2-Propene-1-thiol belongs to the class of organic compounds known as allyl sulfur compounds. Allyl sulfur compounds are compounds containing an allylsulfur group, with the general structure H2C(=CH2)CS. 2-Propene-1-thiol is an alliaceous, garlic, and onion tasting compound. 2-Propene-1-thiol has been detected, but not quantified in, several different foods, such as onion-family vegetables, green onion, red onion, soft-necked garlics (Allium sativum L. var. sativum), and garden onion (var.). This could make 2-propene-1-thiol a potential biomarker for the consumption of these foods. Based on a literature review a small amount of articles have been published on 2-Propene-1-thiol.
