Physiological functions of galactolipids in the photosynthetic membranes

为了了解半乳糖脂的生理功能，在光合膜中占主导地位的膜脂质，我们试图取代这些脂质的其他糖和磷酸脂。二半乳糖基二酰甘油可以被葡萄糖基半乳糖基二酰甘油取代，但不能被磷脂酰胆碱取代。这些结果表明，在目前的光合膜系统中，至少有一部分糖脂可以通过结构相似的糖脂进行生理补充。

To understand physiological function of the galactolipids, dominant membrane lipids in the photosynthetic membranes, we tried to substitute those lipids to other glyco- and phospho-lipids. Digalactosyldiacylglycerol could be substituted by glucosylgalactosyldiacylglycerol, but not by phosphatidylcholine. These results suggest that at least a part of glycolipids in the current photosynthetic membrane systems can be physiologically complemented by structurally similar glycolipids.
