背景資料

Monogalactosyldiglyceride (MGDG) is one of the main lipids of chloroplast membranes and is one of the most abundant lipids in all photosynthetic tissues, including those of algae and some bacteria. In plants it is much less prevalent in nonphotosynthetic tissues and is synthesized by MGDG synthase localized in chloroplast envelope membranes.1 MGDG is formed by the de-phosphorylation of phosphatidic acid or phosphatidylcholine and the subsequent reaction with 5- diphosphate(UDP)-galactose. Monogalactosyldiglycerides do not form a lipid bilayer in the lipid membrane whereas digalactosyldiglycerides (DGDG) do and a proper ratio of these two diglycerides is critical to membrane function. MGDG is an important lipid in photosynthesis although its role is not fully understood and is undergoing much active research.2 In cells undergoing photosynthesis the photosystem I complex contains three moles of MGDG and one mole of phosphatidylglycerol while photosystem II contains four moles of DGDG. The proper ratio of lipids is needed for the effective crystallization of the light-harvesting complex II. MGDG plays an important role in the organization and activity of the embedded protein supercomplexes of the thylalkoid membrane of photosystem II and it helps to maintain an optimum lipid:protein ratio.3
