Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Pentadecenoic acid is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Pentadecenoic acid can be found in black elderberry, black walnut, and common buckwheat, which makes pentadecenoic acid a potential biomarker for the consumption of these food products.
