Utilization of labeled proline by the yeast Candida utilis has been studied. Conversion of the labeled material to biochemically related compounds was observed in the metabolic pools in this organism. The kinetic flow of these molecules into protein was observed, and an explanation is proposed in terms of the absolute cellular concentrations and specific activities of the precursors.
