IUPAC 名称

(4R)-7-[(2R)-6-hydroxy-2,7,8-trimethyl-3,4-dihydro-2H-1-benzopyran-2-yl]-4-methylheptanoic acid

描述

7'-Carboxy-gama-tocopherol is a dehydrogenation carboxylate product of 7'-hydroxy-r-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. [HMDB]
