An inward movement of choline can be demonstrated across isolated skins of Rana pipiens when the outside is bathed by a saline made with choline chloride. This is in contrast to an earlier report indicating that skins of R. esculenta are impermeable to choline. The flux was very small and independent of the active transport of sodium by the skins. For most experiments choline can be used as an "inert" replacement for sodium in this prepration.
当用含有氯化胆碱的盐溶液浸泡牛蛙离体皮肤的外部时，可以证明胆碱会向内移动。这与早期的一份报告相反，该报告表明食用蛙的皮肤对胆碱是不可渗透的。通量非常小，且与皮肤对钠的主动转运无关。在大多数实验中，胆碱可以用作该制剂中钠的“惰性”替代物。
