SELENOAMINO ACIDS: DECREASE OF RADIATION DAMAGE TO AMINO ACIDS AND PROTEINS

F SHIMAZU et al. Science. .

Abstract

Selenomethionine and selenocystine protect amino acid and protein systems from radiation damage. Selenoamino acids are more powerful protectors than the analogous sulfur amino acids and other known -SH protectors. Free-radical scavenger and repair mechanisms by which selenoamino acids react with induced free radicals may be the key reactions in the biological function of logical function of selenium.
