Cyanidin, also known as cyanidin chloride (CAS: 528-58-5), belongs to the class of organic compounds known as 7-hydroxyflavonoids. These are flavonoids that bear one hydroxyl group at the C-7 position of the flavonoid skeleton. Thus, cyanidin is considered to be a flavonoid lipid molecule. Cyanidin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Cyanidin (and its glycosides) is the most commonly occurring of the anthocyanins, a widespread group of pigments responsible for the red-blue colour of many fruits and vegetables (PMID: 14711454). BioTransformer predicts that cyanidin is a product of cyanidin 3-​glucoside metabolism via a glycoside-hydrolysis reaction occurring in human gut microbiota and catalyzed by the EC.3.2.1.X enzyme (PMID: 30612223). Widely distributed anthocyanidin, found especies in Vaccinium subspecies (blueberries, bilberries, whortleberries), cherries, raspberries, red onions, red wine and black tea. Cyanidin is found in many foods, some of which are papaya, hyacinth bean, sweet basil, and abalone. Cyanidin cation is an anthocyanidin cation that is flavylium substituted at positions 3, 3', 4', 5 and 7 by hydroxy groups. It has a role as a metabolite, a neuroprotective agent and an antioxidant. It is a conjugate acid of a cyanidin(1-).
