Metabolite Identification
Common Namegamma-Tocopherol
Descriptiongamma-Tocopherol, also known as 7,8-dimethyltocol, belongs to the class of organic compounds known as tocopherols. These are vitamin E derivatives containing a saturated trimethyltridecyl chain attached to the carbon C6 atom of a benzopyran ring system. They differ from tocotrienols which contain an unsaturated trimethyltrideca-3,7,11-trien-1-yl chain. It is estimated that 50% of gamma-tocopherol is metabolized into gamma-CEHC and excreted into the urine. gamma-Tocopherol is the predominant form of vitamin E in plant seeds and derived products (e.g. nuts and vegetable oils). Unlike alpha-tocopherol, gamma-tocopherol inhibits cyclooxygenase activity and, therefore, exhibit anti-inflammatory properties (PMID: 11722951 ).
