Secondary Accession NumbersNone
Metabolite Identification
Common NameTritriacontanoic acid
DescriptionPsyllic acid, also known as psyllate, belongs to the class of organic compounds known as very long-chain fatty acids. These are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. Based on a literature review very few articles have been published on Psyllic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Tritriacontanoic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Tritriacontanoic acid 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.
