What is the structure of Vaccenic acid?
C18H34O2
Vaccenic acid/Formula
How are oleic acid and elaidic acid different?
Oleic acid and elaidic acid are cis-trans isomers of each other. 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. Moreover, oleic acid is the cis isomer of elaidic acid.
Is Vaccenic acid an unsaturated fatty acid?
It is a monounsaturated fatty acid (one trans double bond; shorthand nomenclature cannot be used to name trans fatty acids) member of the sub-group called long chain fatty acids (LCFA) (from 14 to 18 carbon atoms). In purified form its melting point is at 44 °C (111.2 °F; 317.15 K).
Why Vaccenic acid is an acid?
Vaccenic acid is a naturally occurring trans fatty acid. It is the predominant kind of trans-fatty acid found in human milk, in the fat of ruminants, and in dairy products such as milk, butter, and yogurt….Vaccenic acid.

What is the source of Vaccenic acid?
Vaccenic acid, an isomer of oleic acid, is the principal ruminant trans fatty acid. It is produced through the biohydrogenation of linoleic acid and α-linolenic acid by microorganisms in the rumen and is found naturally in foods such as dairy and ruminant meat products.
Why is Vaccenic acid an acid?
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 Vaccenic acid saturated or unsaturated?
Oxidation of omega-7 unsaturated fatty acids on the skin surface, such as palmitoleic acid and vaccenic acid, may be the cause of the phenomenon commonly known as old person smell.
Is Vaccenic acid saturated monounsaturated or polyunsaturated?
