웹2024년 5월 1일 · For bambusuril 1, addition of monensin gives a clear increase in the rate of transport as seen from the comparison of the green to the blue curves in Figure 6b and S14. This increase can be understood from the combined effect of mechanism A by 1 and mechanism B by monensin, leading to a higher rate of apparent transport of HCO 3 − than … 웹2024년 6월 11일 · Beilstein J.
