When aqueous solutions of adenosine-5'-mono-, di-, or triphosphates are treated with a water soluble carbodiimide the major product is the expected diadenosine-5'-5'-polyphosphate. The yields of these pyrophosphates are greatly increased in the presence of the Mg2+ ion. Adenosine-5'-tetraphosphate behaves differently. The major product is adenosine-5'-monophosphate. We believe that this hydrolysis occurs via a cyclic trimetaphosphate intermediate.
当腺苷 - 5'-单磷酸、二磷酸或三磷酸的水溶液用一种水溶性碳二亚胺处理时,主要产物是预期的5'-5'-二腺苷多磷酸。在Mg2 +离子存在下,这些焦磷酸盐的产率大大提高。腺苷 - 5'-四磷酸的行为不同。主要产物是腺苷 - 5'-单磷酸。我们认为这种水解是通过环状三偏磷酸中间体发生的。
