Abstract
Spinach chloroplasts capable of high rates of CO2 fixation have been isolated in glycinebetaine as an alternative osmoticum to sorbitol and found to be very stable. Proline was a less satisfactory alternatine. The possible significance of the use of glycinebetaine is discussed as this solute may be the physiological cytoplasmic osmoticum in members of the Chenopodiaceae.
摘要
已从菠菜叶绿体中分离出甘氨酸甜菜碱作为替代山梨醇的高 CO2 固定率的渗透物，并发现其非常稳定。脯氨酸是一种不太理想的替代物。甘氨酸甜菜碱的使用可能具有重要意义，因为这种溶质可能是藜科植物细胞质的生理渗透物。
