The Turnover Of 75-Selenium - Selenomethionine As An Indicator Of The Status Of Protein Metabolism In Reindeer (Rangifer Tarandus) (Degradation Rate, Reincorporation, Reutilization)
Dissertation (Ph.D.) University of Alaska Fairbanks, 1983 The turnover of a single injection of ('75)Se-selenomethionine (('75)SeM), a radio-labeled seleno-analog of the amino acid methionine was used to estimate protein turnover, the irreversible loss of protein nitrogen, in reindeer. (...
