What is the difference between oleic acid and elaidic acid?
The key difference between oleic acid and elaidic acid is that oleic acid occurs in the liquid phase, whereas elaidic acid occurs in the solid form. Both these are unsaturated fatty acids because they have a double bond at the middle of the carbon chain. Oleic acid and elaidic acid are cis-trans isomers of each other.
What is the difference between linoleic acid and oleic acid?
Linoleic acid is lightweight and thinner than oleic acid, which means it is able to be absorbed by the skin more easily. This means that oils with higher percentages of linoleic acid are beneficial in controlling acne. Oleic acid, on the other hand, is thicker and feels rich, benefitting those with dry or aging skin.
What is elaidic acid used for?
Elaidic acid increases plasma cholesterylester transfer protein (CETP) activity which lowers HDL cholesterol.
What is the difference between stearic acid and oleic acid?
The key difference between stearic acid and oleic acid is that stearic acid is a saturated compound, while oleic acid is an unsaturated compound. Stearic acid and oleic acid are organic compounds having carbon chains. These are classified as fatty acids according to their chemical structures.
Why does elaidic acid have a higher melting point than oleic acid?
Elaidic acid is a trans fatty acid, and the carbon chains can pack together almost as tightly as those of the saturated stearic acid. Oleic acid is a cis fatty acid, and the bend in the hydrocarbon chain keeps these carbon chains from packing as closely together; fewer interactions lead to a much lower melting point.
How is elaidic acid formed?
Elaidic acid is also produced by partial hydrogenation of polyunsaturated fats for the manufacture of margarines and shortenings. These hydrogenated products contain other cis and trans isomers of monounsaturated fatty acids in which the double bond has migrated between the carbon-8 and carbon-12 positions.
Is linoleic and linolenic acid the same?
Linoleic acid is an essential fatty acid and is an omega-6 fatty acid. This is in contrast to α-linolenic acid (“longer name”), which is an omega-3 fatty acid. Both are essential fatty acids and the body is unable to synthesize them.
What is elaidic acid found in?
Elaidic acid (EA) is an oleic acid trans isomer (trans-9-18:1). It is the predominant trans fatty acid in the Western diet. EA is found in margarine, partially hydrogenated vegetable oils, and fried foods.
What is similar to oleic acid?
Oleic acid resulted in the highest yield whereas oleyl alcohol is the closest candidate for alternative DCA production.
What is the difference between linoleic and stearic acid?
Stearic acid is a typical long chain saturated fatty acid. Oleic acid is a typical monounsaturated fatty acid. Linoleic acid is a typical polyunsaturated fatty acid.
What is elaidic acid?
Elaidic acid, the most abundant trans fatty acid in diet, appears to have an adverse effect on health. A reaction that converts oleic acid to elaidic acid is called elaidinization . Another naturally occurring isomer of oleic acid is petroselinic acid .
How do you convert oleic acid to elaidic acid?
A reaction that converts oleic acid to elaidic acid is called elaidinization . Another naturally occurring isomer of oleic acid is petroselinic acid . In chemical analysis, fatty acids are separated by gas chromatography of their methyl ester derivatives.
Is elaidic acid a trans fat?
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. It is the trans isomer of oleic acid. The name of the elaidinization reaction comes from elaidic acid.
What is oleic acid?
From Wikipedia, the free encyclopedia Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 cis -9.
