Metabolite Identification
Common Name1-Propanethiol
Description1-Propanethiol, also known as 1-propylmercaptan or N-propylthiol, belongs to the class of organic compounds known as alkylthiols. These are organic compounds containing the thiol functional group linked to an alkyl chain. 1-Propanethiol is a sweet, cabbage, and gassy tasting compound. 1-Propanethiol has been detected, but not quantified in, several different foods, such as common peas (Pisum sativum), common beans (Phaseolus vulgaris), wild leeks (Allium ampeloprasum), green onion, and fruits. This could make 1-propanethiol a potential biomarker for the consumption of these foods. 1-Propanethiol is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on 1-Propanethiol.
