Broader concept

Entry terms

  • 3,4-Dihydro-2,5,7,8-tetramethyl-2-(4,8,12-trimethyltridecyl)-2H-1-benzopyran-6-ol

Note

  • deficiency: coordinate ALPHA-TOCOPHEROL with VITAMIN E DEFICIENCY

Scope note

  • A natural tocopherol and one of the most potent antioxidant tocopherols. It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. It has four methyl groups on the 6-chromanol nucleus. The natural d form of alpha-tocopherol is more active than its synthetic dl-alpha-tocopherol racemic mixture.

History note

  • 2002; use VITAMIN E 1966-2001; for ALPHA-TOCOPHEROL SUCCINATE use VITAMIN E 1982-2007; for TOCOPHEROL ACETATE, D-ALPHA-TOCOPHEROL ACETATE, and TOCOPHEROL SUCCINATE use TOCOPHEROLS 2008-2013
