Abstract
IT is generally required in radioactive tracer procedure when applied to biochemical problems that the stable and radioactive molecules or ions possess identical configurations. Only when the two isotopic atoms are supplied in the same chemical form can it be assumed that living tissues will absorb them in the proportions applied. In experiments carried out here with phosphorus-32, it was found that this requirement was not satisfied, and since no information is available on the selectivity of the plants to isotopic elements in different chemical forms, our data cannot be interpreted.
