Metabolite Identification
Common NameEthyl isopropyl disulfide
DescriptionEthyl isopropyl disulfide belongs to the class of organic compounds known as dialkyldisulfides. These are organic compounds containing a disulfide group R-SS-R' where R and R' are both alkyl groups. Ethyl isopropyl disulfide has been detected, but not quantified in, several different foods, such as garden onion (var.), onion-family vegetables, welsh onions (Allium fistulosum), red onion, and garden onions (Allium cepa). This could make ethyl isopropyl disulfide a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Ethyl isopropyl disulfide.
