Metabolite Identification
Common Nametrans-2-Hexenyl propanoate
Descriptiontrans-2-Hexenyl propanoate is a member of the class of compounds known as carboxylic acid esters. Carboxylic acid esters 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). trans-2-Hexenyl propanoate is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). trans-2-Hexenyl propanoate is used as a food additive (EAFUS: Everything Added to Food in the United States). trans-2-Hexenyl propanoate is a flavouring ingredient and has an apple and fruity taste.
