Sulfur Amino Acids, Vitamin E, and Free Radical Peroxidation

Intekkelationships of Sulfur Amino Acids, Vitamin E, and Free Radical Peroxidation 

The nutritional relationships between sulfur amino acids and proteins and vitamin E are well known. Low sulfur amino acid diets are used in 

The alkylperoxyl radical can be expected to react with sulfur amino acids by mechanisms similar to those for HOO- and HO-. Reactions of the hydroxyl and hydroperoxyl radicals have been more extensively studied because of their importance in radiation biochemistry. Thus, for cysteine, glutathione, and sulfhydryl proteins, 

In the animal body these oxidation products are on the normal metabolic pathway for oxidation of cysteine and cystine, so they cannot be used as a 

Since sulfoxide and sulfone are not normal intermediates in the oxidative metabolism of methionine, experimental tests of these reactions in vivo should be profitable.
