Erucic acid, vegetable oil acid, arachidonic acid, behenic acid, arachidic acid, oleic acid, stearic acid, palmitic acid, etc.
1, erucic acid: colorless needle crystal. Very soluble in ether, soluble in ethanol and methanol, insoluble in water.
2. Vegetable oil acid: It is a monounsaturated Omega-9 fatty acid, which exists in animals and plants. Hydroaddition of oleic acid to obtain stearic acid. The double bond trans isomer of oleic acid is called trans oleic acid.
3. Arachidonic acid: It is cis-5,8,11,14-eicosatetraenoic acid, with the chemical formula of C20H32O2, which belongs to unsaturated fatty acid, and contains four carbon-carbon double bonds and one carbon-oxygen double bond, and is a higher unsaturated fatty acid. Widely distributed in the animal kingdom, a small amount exists in glycerides of a certain species, and can also be found in glycerophosphates. Linoleic acid can be synthesized in human body. It is inferred that it is one of the initiators of prostaglandin biosynthesis.
4. behenic acid: it is a high carbon chain fatty acid with the longest carbon chain in nature. Because of its long carbon chain, it has more stable characteristics than other short carbon chain fatty acids. Insoluble in water, slightly soluble in ether and ethanol. Non-toxic
5. Arachic acid: Arachic acid exists in some oils, and its content is about 1% or lower. Peanut oil contains 2.4% Arachic acid. Glossy white flaky crystals.
