描述
Elaidic acid, also known as trans-9-octadecenoic acid or elaidate, 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. Thus, elaidic acid is considered to be a fatty acid lipid molecule. Elaidic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Elaidic acid can be synthesized from trans-octadec-9-ene. Elaidic acid is also a parent compound for other transformation products, including but not limited to, ricinelaidic acid, hexadecyl elaidate, and cystodytin H. Elaidic acid can be found in fats and oils and pomegranate, which makes elaidic acid a potential biomarker for the consumption of these food products. Elaidic acid can be found primarily in blood and feces, as well as in human adipose tissue and fibroblasts tissues. Elaidic acid is the organic compound with the formula CH3(CH2)7CHCH(CH2)7CO2H. Classified as an unsaturated trans fatty acid, it is a colorless oily solid. This compound has attracted attention because it is a major trans fat found in hydrogenated vegetable oils, and trans fats are implicated in heart disease .
