Natural Product Identification
Common NameS-Methyl 3-methylthiobutyrate
DescriptionS-Methyl 3-methylthiobutyrate, also known as fema 3864 or methanethiol isovalerate, belongs to the class of organic compounds known as fatty acyl thioesters. These are thioester derivatives of a fatty acid with the general formula RC(=O)SR', where R is the fatty acyl chain. S-Methyl 3-methylthiobutyrate is an extremely weak basic (essentially neutral) compound (based on its pKa). S-Methyl 3-methylthiobutyrate is an acrid, cheese, and fermented tasting compound. Outside of the human body, S-Methyl 3-methylthiobutyrate has been detected, but not quantified in, fruits and milk and milk products. This could make S-methyl 3-methylthiobutyrate a potential biomarker for the consumption of these foods.
