Abstract
Spin-lattice relaxation times T(1) in deuterated aqueous dispersions of lecithin and rod outer segment disk membranes were measured at various concentrations and temperatures. Fast chemical exchange between two loosely defined phases of water molecules was shown to fit the data, allowing the dynamic features of "bound" water and the hydration of the biological membrane to be evaluated. The state of the water was shown to be also involved in vision physiology.
摘要
在不同浓度和温度下，测量了卵磷脂和视杆外段盘膜的氘代水分散体中的自旋晶格弛豫时间T(1)。结果表明，水分子两个大致定义的相之间的快速化学交换符合数据，从而能够评估“结合”水的动态特征和生物膜的水化作用。研究还表明，水的状态也与视觉生理学有关。
