13'-Hydroxy-gamma-tocopherol
IUPAC 名称
(2R)-2-[(4S,8R)-13-hydroxy-4,8,12-trimethyltridecyl]-2,7,8-trimethyl-3,4-dihydro-2H-1-benzopyran-6-ol
描述
13'-hydroxy-r-tocopherol is a precursor of dehydrogenation to form 13'-Carboxy-gama-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]
