|January 1, 1974
Abstract:
The effect of selenourea and of colloidal selenium on dilute aqueous solutions of the enzyme yeast alcoholdehydrogenase and on suspensions of E. coli B/r has been studied. Selenourea usually appears to protect meanwhile colloidal selenium radiosensitizes. The results are considered in terms of chemical stability of selenourea and of its free radical reactivity.
