Metabolite Identification
Common Name15-KETE
Description15-KETE, also known as 15-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, 15-KETE is considered to be an eicosanoid. Based on a literature review a significant number of articles have been published on 15-KETE.
