• <I>cyclo</I>-Tetraphosphate (P<SUB>4m</SUB>) reacted with L-valine at pH 12 to form a certain phosphorus-containing compound (Compound X). Compound X was obtained in amounts so small as about 3.2% at room temperature after 91 d and about 0.3% at 70 °C after 1 d. Based on the results of paper chromatography, anion-exchange chroma-tography, and IR spectroscopy, Compound X was proved to be the same orthophosphate derivative of valine, an anion of <I>N</I>-(1-carboxy-2-methylpropyl)phosphoramidic acid, as that formed by the reaction of <I>cyclo</I>-triphosphate (P<SUB>3m</SUB>) with L-valine. The mechanism of the reaction of P<SUB>4m</SUB> with L-valine was discussed.
