Common Name

Octadec-9-enoic Acid

Description

Octadec-9-enoic Acid, also known as 18:1, N-9 or Delta(9)-Octadecenoic acid, is classified as a member of the Long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Octadec-9-enoic Acid is considered to be practically insoluble (in water) and acidic. Octadec-9-enoic Acid can be synthesized from octadec-9-ene. It is also a parent compound for other transformation products, including but not limited to, 1-octadec-9-enoylglycero-3-phosphate, N-(2-hydroxy-1-methylethyl)-9-octadecenamide, and sterculic acid
