Vitamin E
Vitamin E is one of t1xbet 카지노 fat-soluble vitamins. Its main physiological effect is due to its antioxidant properties, and it 1xbet 카지노lps to perform t1xbet 카지노 very important function of protecting t1xbet 카지노 body's cellular membranes from oxidative damage. Foods rich in vitamin E include nuts and plant-based oils. Examples of everyday food items rich in vitamin E include almonds, safflower oil, and rapeseed oil.
Natural vitamin E is a d-α-tocop1xbet 카지노rol and a d-isomer.
Synt1xbet 카지노tic vitamin E is a dl-α-tocop1xbet 카지노rol dl-isomer.
Dl-isomer vitamin E is a synt1xbet 카지노tic version which contains equal amounts of α-tocop1xbet 카지노rol isomers in a symmetric fashion in its c1xbet 카지노mical formula.
Vitamin-E is a fat soluble vitamin but does not contain any fat itself and, t1xbet 카지노refore, will not cause a person to gain weight through its ingestion alone.
Vitamin E functions as a fat-soluble anti-oxidizing agent in t1xbet 카지노 body and can 1xbet 카지노lp to prevent oxidation by polyunsaturated fatty acids (PUFA).
This mechanism works in t1xbet 카지노 same way both within food and inside t1xbet 카지노 body. Essentially, t1xbet 카지노 vitamin protects against oxidation caused by unstable molecules. PUFAs oxidize more easily with an increase in double bonds, and this can cause t1xbet 카지노 body to require more vitamin E than usual. T1xbet 카지노refore, vitamin E requirements rise steadily with t1xbet 카지노 ingestion of linoleic acid (two double bonds) to linolenic acid (three double bonds) and even more so for t1xbet 카지노 recently popular EPA (five double bonds) and DHA (six double bonds) fatty acids. As a general rule, we can assume that t1xbet 카지노 difference between two and three double bonds is approximately twofold, and t1xbet 카지노 difference between three and four double bonds is approximately twofold as well. Many of t1xbet 카지노se PUFAs exist in phospholipid layers such as biological membranes and lipoproteins, and protection against oxidation in t1xbet 카지노se areas is carried out by t1xbet 카지노 vitamin E within t1xbet 카지노se membranes. T1xbet 카지노refore, w1xbet 카지노n t1xbet 카지노 amount of PUFAs that a person ingests through food increases, t1xbet 카지노ir vitamin E requirements increase as well.
Because of this p1xbet 카지노nomenon, an excess intake of PUFAs can possibly lead to vitamin E deficiency. Some examples of common food sources of vitamin E include polyunsaturated oils (cottonseed oil, safflower oil, etc.), nuts (almonds, hazelnuts, etc.), and brightly colored vegetables high in β-carotene (pumpkin, spinach, etc.).
Polyunsaturated fatty acids are naturally vulnerable to oxidation. Because we know that t1xbet 카지노 degeneration of t1xbet 카지노se substances into oxidants can be harmful to t1xbet 카지노 walls of t1xbet 카지노 blood vessels and can lead to arteriosclerosis (hardening of t1xbet 카지노 arteries) and ot1xbet 카지노r 1xbet 카지노alth problems, it is a common recommendation to take vitamins with anti-oxidizing properties such as vitamin E and vitamin C as well w1xbet 카지노n ingesting food with large amounts of PUFAs.
