Metabolite Identification
Common Namexi-1-(Propylthio)-1-propanethiol
Descriptionxi-1-(Propylthio)-1-propanethiol, also known as 1-(propylsulphanyl)propane-1-thiol, belongs to the class of organic compounds known as hemiacetals. Hemiacetals are compounds comprising the hemiacetal functional group, with the general formula R2C(OH)OR' ( R' not Hydrogen ). xi-1-(Propylthio)-1-propanethiol has been detected, but not quantified in, several different foods, such as green onion, garden onion (var.), garden onions (Allium cepa), welsh onions (Allium fistulosum), and onion-family vegetables. This could make XI-1-(propylthio)-1-propanethiol a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on xi-1-(Propylthio)-1-propanethiol.
