Metabolite Identification
Common Name7'-Carboxy-alpha-tocotrienol
Description7'-Carboxy-alpha-tocotrienol is a dehydrogenation carboxylate product of 7'-hydroxy-a-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.
