描述
Petroselinic acid, also known as (6z)-petroselinate or (Z)-6-octadecenoate, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Petroselinic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Petroselinic acid can be found in a number of food items such as jicama, common salsify, orange bell pepper, and cardoon, which makes petroselinic acid a potential biomarker for the consumption of these food products. Petroselinic acid can be found primarily in blood. Petroselinic acid is a fatty acid that occurs naturally in several animal and vegetable fats and oils. It is a white powder and is commercially available. In chemical terms, petroselinic acid is classified as a monounsaturated omega-12 fatty acid, abbreviated with a lipid number of 18:1 cis-6. It has the formula CH3(CH2)10CH=CH(CH2)4COOH. The term "petroselinic" means related to, or derived from, oil of Petroselinum, parsley. Petroselinic acid is an positional isomer of oleic acid .
