Elaidic acid has 18 carbons and is a trans-9-mono-unsaturated fatty acid. It is also a trans isomer of oleic acid. C 17 H 33 CO 2 H, IUPAC organization name (E)-octadec-9-enoic acid, numerical representation 18:1 (9), n-9, molecular weight 282.46, melting point 43–45 °C. CAS Registry Number 112-79-8.

Stearic acid is a prevalent fatty-acid in nature, found in many animal and vegetable fats, but is usually higher in animal fat than vegetable fat. It has a melting point of 69.4 °C (156.9 °F) °C and a pKa of 4.50. [11] Its name comes from the Greek word στέαρ "stéar", which means tallow.
In either numbering scheme, the position of a double bond in a fatty acid chain is always specified by giving the label of the carbon closest to the carboxyl end. [d] Thus, in an 18 carbon fatty acid, a double bond between C-12 (or ω−6) and C-13 (or ω−5) is said to be "at" position C-12 or ω−6. The IUPAC naming of the acid, such as ...
It can be produced by the hydrogenation of oleic acid esters by Bouveault–Blanc reduction, which avoids reduction of the C=C group (as would occur with usual catalytic hydrogenation). The required oleate esters are obtained from beef fat , fish oil , and, in particular, olive oil (from which it gains its name).
Elaidic acid is an unsaturated trans fatty acid, with code C18:1 trans-9. This compound has attracted attention because it is a major trans fat found in hydrogenated vegetable oils, and trans fats have been implicated in heart disease. [1] It is the trans isomer of oleic acid. The name of the elaidinization reaction comes from elaidic acid.
