Metabolite Identification
Common NameMethylthiomethyl hexanoate
DescriptionMethylthiomethyl hexanoate, also known as fema 3880 or hexanoic acid, (methylthio)methyl ester, is a member of the class of compounds known as fatty acid esters. Fatty acid esters are carboxylic ester derivatives of a fatty acid. Thus, methylthiomethyl hexanoate is considered to be a fatty ester lipid molecule. Methylthiomethyl hexanoate is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Within the cell, methylthiomethyl hexanoate is primarily located in the membrane (predicted from logP). It can also be found in the extracellular space. Methylthiomethyl hexanoate is a flavouring agent for baked goods, seasonings etc..
