Differences in colligative properties (freezing point, boiling point, vapor pressure and osmotic behavior) between water in living cells and pure bulk water were investigated by re-evaluating reports of the osmotic behavior of mammalian cells. In five different animal cells, osmotically unresponsive water (OUW) values ranged from 1.1 to 2.2 g per g dry mass. Detailed analysis of human red blood cell (RBC) data indicates a major role for hemoglobin OUW-values, aggregation and packing in cell volume regulation that can be explained for the first time in relevant molecular terms.
通过重新评估哺乳动物细胞渗透行为的报告，研究了活细胞中的水与纯大量水之间在依数性（冰点、沸点、蒸气压和渗透行为）方面的差异。在五种不同的动物细胞中，每克干质量的非渗透响应水（OUW）值在1.1至2.2克之间。对人类红细胞（RBC）数据的详细分析表明，血红蛋白的OUW值、聚集和堆积在细胞体积调节中起主要作用，这首次可以用相关分子术语来解释。
