Metabolite Identification
Common Name3-Methylbutyl propanoate
Description3-Methylbutyl propanoate, also known as isopentyl propanoate or 3-methylbutyl propionic acid, belongs to the class of organic compounds known as carboxylic acid esters. These are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom (forming an ester group). 3-Methylbutyl propanoate is a sweet, banana, and bitter tasting compound. 3-Methylbutyl propanoate has been detected, but not quantified in, apples (Malus pumila) and roman camomiles (Chamaemelum nobile). This could make 3-methylbutyl propanoate a potential biomarker for the consumption of these foods. 3-Methylbutyl propanoate 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 small amount of articles have been published on 3-Methylbutyl propanoate.
