Metabolite Identification

Common Name

S,S'-Ethylidene dithioacetate

Description

S,S'-Ethylidene dithioacetate belongs to the class of organic compounds known as dithioacetals. Dithioacetals are compounds containing a dithioacetal functional group with the general structure R2C(SR')2. S,S'-Ethylidene dithioacetate has been detected, but not quantified in, citrus. This could make S,s'-ethylidene dithioacetate a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on S,S'-Ethylidene dithioacetate.
