Abstract
It has been shown that when yeast is fractionated by repeated extractions with cold trichloracetic acid a species of phosphate, found in both the acid-soluble and the residue fractions, is identifiable as metaphosphate1,2. The co-existence in a yeast cell of metaphosphate in both acid-soluble and acid-insoluble forms suggests the possibility that these two may differ in their metabolic and physiological function. It is the purpose of the present note to report some recent observations which indicate that this is the case.
