热力学参数的结合的一价阳离子，Li+，Na+，K+，Rb+，Cs+，NH 4+，TI+，和Ag+，短杆菌肽A和短杆菌肽C，纳入溶血磷脂酰胆碱的TI+的结合，已确定使用TI-205核磁共振光谱和竞争结合的组合。的热力学参数，焓和熵，进行了讨论的过程中涉及的阳离子从水溶液到酰胺环境的转移。
Thermodynamic parameters for the binding of the monovalent cations, Li+, Na+, K+, Rb+, Cs+, NH4+, TI+, and Ag+, to gramicidin A and for the binding of TI+ to gramicidin C, incorporated into lysophosphatidylcholine, have been determined using a combination of TI-205 nuclear magnetic resonance spectroscopy and competition binding. The thermodynamic parameters, enthalpy and entropy, are discussed in terms of a process involving the transfer of cations from an aqueous to amide environment.
