Descriptor English: beta-Tocopherol
Descriptor Spanish: beta-Tocoferol
Descriptor beta-tocoferol
Scope note: Tocoferol natural con menor actividad antioxidante que el alfa-tocoferol. Su capacidad antioxidante se debe al hidrógeno fenólico en el núcleo 2H-1-benzopirano-6-ol. Como el GAMMA-TOCOFEROL, este compuesto también tiene tres grupos metilo en el núcleo 6-cromanol, pero en diferentes sitios.

RDF Unique Identifier: https://id.nlm.nih.gov/mesh/D024503
Scope note: A natural tocopherol with less antioxidant activity than alpha-tocopherol. It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. As in GAMMA-TOCOPHEROL, it also has three methyl groups on the 6-chromanol nucleus but at different sites.
