| Common Name | 15-Methylpalmitate |
|---|
| Description | 15-Methylpalmitate, also known as C17:0 or iso-margaric 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. 15-Methylpalmitate is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. |
