Metabolite Identification
Common NameCetyl palmitate
DescriptionCeryl palmitate, also known as we(16:0/16:0), belongs to the class of organic compounds known as wax monoesters. These are waxes bearing an ester group at exactly one position. Based on a literature review a small amount of articles have been published on Ceryl palmitate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Cetyl palmitate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Cetyl palmitate is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
