Common Namedelta-Tocopherol
DescriptionDelta-Tocopherol, also known as δ-tocopherol or 8-methyltocol, belongs to the class of organic compounds known as tocopherols. These are vitamin E derivatives containing a saturated trimethyltridecyl chain attached to the carbon C6 atom of a benzopyran ring system. The differ from tocotrienols that contain an unsaturated trimethyltrideca-3,7,11-trien-1-yl chain. Thus, delta-tocopherol is considered to be a quinone. Delta-Tocopherol exists in all living organisms, ranging from bacteria to humans. Delta-Tocopherol has been detected, but not quantified in, several different foods, such as yams (Dioscorea), arabica coffees (Coffea arabica), mammee apples (Mammea americana), chestnuts (Castanea), and dills (Anethum graveolens). This could make delta-tocopherol a potential biomarker for the consumption of these foods. Delta-Tocopherol is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. It was first documented in 1999 (PMID: 10385606). Based on a literature review a significant number of articles have been published on delta-Tocopherol (PMID: 17984079) (PMID: 14695946) (PMID: 16400056) (PMID: 12600864).
