Common Namecis-Vaccenic acid
Descriptioncis-11-Octadecenoic acid, also known as (Z)-octadec-11-enoic acid or asclepic acid, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. cis-11-Octadecenoic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral.
