Metabolite Identification
Common NameDieckol
Descriptiondieckol belongs to the class of organic compounds known as tannins. These are naturally occurring polyphenols which be categorized into four main classes: hydrolyzable tannin (based on ellagic acid or gallic acid), condensed tannins (made of oligomeric or polymeric proanthocyanidins), complex tannins (made of a catechin bound to a gallotannin or elagitannin), and phlorotannins (oligomers of phloroglucinol). dieckol is an extremely weak basic (essentially neutral) compound (based on its pKa). A phlorotannin isolated from a brown alga Ecklonia cava which exhibits antioxidant, hepatoprotective and anticoagulant activities. This compound has been identified in human blood as reported by (PMID: 31557052 ). Dieckol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Dieckol 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.
