Metabolite Identification
Common NamePentanal
DescriptionPentanal, also known as N-valeraldehyde or amyl aldehyde, belongs to the class of organic compounds known as alpha-hydro gen aldehydes. These are aldehydes with the general formula HC(H)(R)C(=O)H, where R is an organyl group. Pentanal is a saturated fatty aldehyde composed from five carbons in a straight chain. Thus, pentanal is considered to be a fatty aldehyde lipid molecule. Pentanal is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Pentanal is an almond, berry, and bready tasting compound. Pentanal is found, on average, in the highest concentration within a few different foods, such as black walnuts, milk (cow), and carrots and in a lower concentration in corns, tortilla, and safflowers. Pentanal has also been detected, but not quantified, in several different foods, such as crustaceans, garden tomato, herbs and spices, and guava. This could make pentanal a potential biomarker for the consumption of these foods.
