Common NameN-Isobutyloctadeca-trans-2-trans-4-dienamide
DescriptionN-isobutyloctadeca-trans-2-trans-4-dienamide is a member of the class of compounds known as N-acyl amines. N-acyl amines are compounds containing a fatty acid moiety linked to an amine group through an ester linkage. Thus, N-isobutyloctadeca-trans-2-trans-4-dienamide is considered to be a fatty amide lipid molecule. N-isobutyloctadeca-trans-2-trans-4-dienamide is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). N-isobutyloctadeca-trans-2-trans-4-dienamide can be found in pepper (spice), which makes N-isobutyloctadeca-trans-2-trans-4-dienamide a potential biomarker for the consumption of this food product.
