The thus-generated tocopheryl radical is recycled to tocopherol by a redox reaction with a hydrogen donor, such as vitamin C. [24] Vitamin E affects gene expression [25] and is an enzyme activity regulator, such as for protein kinase C (PKC) – which plays a role in smooth muscle growth – with vitamin E participating in deactivation of PKC ...
Ascorbyl palmitate is an ester formed from ascorbic acid and palmitic acid creating a fat-soluble form of vitamin C. In addition to its use as a source of vitamin C, it is also used as an antioxidant food additive (E number E304). It is approved for use as a food additive in the EU, [1] the U.S., [2] Canada, [3] Australia, and New Zealand. [4]
Vitamin C (ascorbic acid) is a water-soluble compound that fulfills several roles in living systems. Sources include citrus fruits (such as oranges, sweet lime, etc.), green peppers, broccoli, green leafy vegetables, black currants, strawberries, blueberries, seabuckthorn, raw cabbage and tomatoes.

The discovery of vitamin E by scientists Katherine Bishop and Herbert Evans in 1922 marked the beginning of the understanding of tocotrienols. [17] Vitamin E was named "tocopherol" (from the Greek words tokos , meaning childbirth, and phero , meaning to bring forth) due to its presumed role in aiding conception.
Many multivitamin formulas contain vitamin C, B 1, B 2, B 3, B 5, B 6, B 7, B 9, B 12, A, E, D 2 (or D 3), K, potassium, iodine, selenium, borate, zinc, calcium, magnesium, manganese, molybdenum, beta carotene, and/or iron. Multivitamins are typically available in a variety of formulas based on age and sex, or (as in prenatal vitamins) based on ...
Grains are more starch based [36] and nuts have a high protein, fibre, vitamin E and B content. [40] Seeds are a good source of food for animals because they are abundant and contain fibre and healthful fats, such as omega-3 fats. [48] [49] Complicated chemical interactions can enhance or depress bioavailability of certain nutrients.
Tocopherols (/ t oʊ ˈ k ɒ f ə ˌ r ɒ l /; [1] TCP) are a class of organic compounds comprising various methylated phenols, many of which have vitamin E activity. Because the vitamin activity was first identified in 1936 from a dietary fertility factor in rats, it was named tocopherol, from Greek τόκος tókos 'birth' and φέρειν phérein 'to bear or carry', that is 'to carry a ...
