| Common Name | 5-KETE |
|---|
| Description | 5-KETE, also known as 5-keto-ete or 5-oxoete, 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. Thus, 5-KETE is considered to be an eicosanoid. Based on a literature review a significant number of articles have been published on 5-KETE. |
