Metabolite Identification
Common NameDihomolinoleic acid
DescriptionDihomolinoleic acid, also known as 10Z,12Z-octadecadienoic acid, is classified as a linoleic acid or a linoleic acid derivative. Linoleic acid is a polyunsaturated omega-6 18-carbon fatty acid with two CC double bonds at the 9- and 12-positions. Dihomolinoleic acid is considered to be practically insoluble (in water) and a very weak acidic compound. Dihomolinoleic acid can be found in black walnut, which makes dihomolinoleic acid a potential biomarker for the consumption of this food product. Dihomolinoleic acid can be found in blood, saliva, and feces.
