on the ribose and deoxyribose may disfavor the formation of T-tetramers, and in the series of alkali metal ions, lithium did not induce T-tetramer due to its small ion size. Sodium, potassium, rubidium and caesium could produce thymidine-based T-tetramers. Furthermore, rubidium and caesium could induce T-pentamers and dimeric T-pentamers probably due to their larger ion sizes.
我们提出了直接的ESI Q-TOF MS和X射线证据,证明它们对基于胸苷的T-四聚体的形成具有显着的结构和金属离子尺寸影响。核糖和脱氧核糖可能不利于T-四聚体的形成,并且在一系列碱金属离子中,锂由于离子尺寸小而没有诱导T-四聚体。钠,钾,rub和铯可产生基于胸苷的T-四聚体。此外,probably和铯可能会诱导T-戊烷和二聚T-戊烷,因为它们的离子尺寸更大。
