D-Alpha Tocopheryl Acetate
11 month agoD-Alpha Tocopheryl Acetate
D-α-Tocopherol acetate, as a crucial component of the cell membrane, plays a pivotal role in maintaining the integrity and function of the cellular structure. Not only is it the primary antioxidant present on the cell membrane, protecting it from oxidative stress, but it also contributes significantly to the overall health and vitality of the cell.
1.In the area of Food & Nutrition, DL-α-Tocopherol acetate is abundantly found in various animal and plant-based foods. Animal-derived foods, primarily, contain the DA type, while vegetable oils are rich in DL-α-tocopherol acetate. The content of this antioxidant is often in parallel with the presence of polyunsaturated fatty acids such as linoleic acid, highlighting its importance in maintaining the stability and quality of these essential fatty acids.
2.Within the category of Vitamins & Minerals, vitamin E is a vital nutrient that the body requires for various biological functions. As an outstanding derivative of vitamin E, DL-α-tocopherol acetate retains many of the beneficial properties of its parent compound. It helps protect cells from damage caused by free radicals, supports immune function, and promotes overall health and well-being.
3.As a Plant Extract, DL-α-tocopherol acetate offers a natural source of antioxidants that can be incorporated into dietary supplements or used in food processing to enhance the nutritional value and shelf life of products. Its yellow, transparent, and viscous oily liquid form, with no odor, makes it an ideal ingredient for various application
