Abstract

Pulsed-gradient 31P NMR was used to measure the diffusion rates of phosphorus compounds in aqueous solution and in living muscles. The diffusion rates of creatine phosphate and inorganic phosphate in intact frog muscle cells were reduced by a factor of approximately 2 from those in aqueous solution, which suggests that the apparent intracellular viscosity is approximately 2 times larger than in aqueous solution.

摘要

脉冲梯度31P核磁共振被用于测量磷化合物在水溶液和活体肌肉中的扩散速率。在完整的青蛙肌肉细胞中,磷酸肌酸和无机磷酸的扩散速率比在水溶液中的扩散速率降低了约2倍,这表明细胞内的表观粘度大约是水溶液中的2倍。
