| Common Name | 13'-Hydroxy-alpha-tocotrienol |
|---|
| Description | 13'-hydroxy-a-tocotrienol is the precursor of dehydrogenation to 13'-carboxy-alpha-tocotrienol by an unidentified microsomal enzyme(s) probably via an aldehyde intermediate. Tocotrienols are members of the vitamin E family. An essential nutrient for the body, vitamin E is made up of four tocopherols (alpha, beta, gamma, delta) and four tocotrienols (alpha, beta, gamma, delta).Chemically, vitamin E is an antioxidant. One model for the function of vitamin E in the body is that it protects cell membranes, active enzyme sites, and DNA from free radical damage. Tocotrienols are natural compounds found in select vegetable oils, wheat germ, barley, saw palmetto, and certain types of nuts and grains. This variant of vitamin E only occur at very low levels in nature. While the majority of research on vitamin E has focused on alpha-tocopherol, studies into tocotrienols account for less than 1% of all research into vitamin E. |

| Chemical Taxonomy |
|---|
| Description | Belongs to the class of organic compounds known as tocotrienols. These are vitamin E derivatives containing an unsaturated trimethyltrideca-3,7,11-trien-1-yl chain attached to the carbon C6 atom of a benzopyran ring system. The differ from tocopherols that contain a saturated trimethyltridecyl chain. |
