The Entry of Selenium into Rabbit Protein Following the Administration of Na275Seo3

Abstract

Recently evidence was offered that selenium supplied orally to lactating ewes, as Na275Se03, was partly incorporated into milk proteins as selenomethionine (Godwin, Handreck, and Fuss 1971). Previous studies, claiming similar conversion of inorganic selenium in animal tissues, have been based on the demonstration of 75Se activity in the vicinity of certain sulphur analogues during chromatographic procedures (McConnell and Wabnitz 1957; Rosenfeld 1962).
