Chemical Information

FooDB Name

Methanedithiol

Description

Methanedithiol belongs to the class of organic compounds known as alkylthiols. These are organic compounds containing the thiol functional group linked to an alkyl chain. Methanedithiol is a pungent tasting compound. Methanedithiol has been detected, but not quantified in, several different foods, such as green onion, red onion, common mushrooms (Agaricus bisporus), garden onions (Allium cepa), and onion-family vegetables. This could make methanedithiol a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Methanedithiol.
