BIOMOLECULES AND ENZYMES

Detailed explanation-1: -As the major vitamin E forms in the food, T and T are more abundant than other tocopherols or tocotrienols in tissues. On the other hand, despite variations in food sources, it has long been observed that T is the predominant form of vitamin E in the body.

Detailed explanation-2: -The main forms in the diet are -and -tocopherol, due to the highest content in food products. Nevertheless, -tocopherol is the main form of vitamin E with the highest tissue concentration. The -forms of both tocopherols and tocotrienols are considered as the most metabolically active.

Detailed explanation-3: -The most biologically active form for mammals is -tocopherol, which is the dominant form of vitamin E found in blood and tissues. The estimated average requirement of -tocopherol for people is 12 mg d−1, but dietary intakes and plasma levels of -tocopherol show considerable inter individual variation.

Detailed explanation-4: -Alpha-tocopherol is being studied in the prevention and treatment of some types of cancer. It is a type of antioxidant. Also called vitamin E.

Detailed explanation-5: -Natural and synthetic alpha tocopherol are different in their composition. The natural form is made up of a molecule with methyl (-CH3) groups at the 2, 4’ and 8’ positions on the chromanol ring. The synthetic form is made up of eight stereoisomers, all with identical antioxidant activity in vitro.
