Description

Catechin, also known as cyanidanol or catechuic acid, belongs to the class of organic compounds known as catechins. Catechins are compounds containing a catechin moiety, which is a 3,4-dihydro-2-chromene-3,5.7-tiol. Catechin also belongs to the group of compounds known as flavan-3-ols (or simply flavanols), part of the chemical family of flavonoids. Catechin is one of the 4 catechin known diastereoisomers. Two of the isomers are in trans configuration and are called catechin and the other two are in cis configuration and are called epicatechin. The most common catechin isomer is the (+)-catechin. The other stereoisomer is (-)-catechin or ent-catechin. The most common epicatechin isomer is (-)-epicatechin. Catechin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Catechin is a bitter tasting compound and is associated with the bitterness in tea. Catechin is a plant secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Catechin is an antioxidant flavonoid, occurring especially in woody plants as both Catechin and (-)-Catechin (cis) forms. Outside of the human body, Catechin is found, on average, in the highest concentration in foods, such as blackcurrants (Ribes nigrum), evergreen blackberries (Rubus laciniatus), and blackberries (Rubus) and in a lower concentration in dills (Anethum graveolens), hot chocolates, and medlars (Mespilus germanica). Catechin has also been detected, but not quantified in, several different foods, such as rice (Oryza sativa), apple ciders, peanuts (Arachis hypogaea), fruit juices, and red teas. This could make catechin a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Catechin.
