| Common Name | 13'-Hydroxy-gamma-tocopherol |
|---|
| Description | 13'-hydroxy-r-tocopherol is a precursor of dehydrogenation to form 13'-Carboxy-gamma-tocopherol by an unidentified microsomal enzyme(s) probably via an aldehyde intermediate. r-Tocopherol provides different antioxidant activities in food and in-vitro studies and showed higher activity in trapping lipophilic electrophiles and reactive nitrogen and oxygen species. From the metabolism end product, only that of r-tocopherol (2,7,8-trimethyl-2-(b-carboxyethyl)-6-hydroxychroman), but not that of a-tocopherol, was identified to provide natriuretic activity. Only the r-tocopherol plasma level served as biomarker for cancer and cardiovascular risk. |

| Chemical Taxonomy |
|---|
| Description | 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. The differ from tocotrienols that contain an unsaturated trimethyltrideca-3,7,11-trien-1-yl chain. |
