Lipid Molecular Species Composition of Granal and Stromal Lamellae
We are investigating the lipid biosynthetic pathways involved in both the development of chloroplast membranes and the lipid-protein interactions in a mature chloroplast. We report the molecular species compositions of monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG) from highly purified granal and stromal lamellae of Splrodela oligorrhiza. Characteristic differences in the lipids suggest that constituent lipid molecular species (formed via different pathways) are associated with the specialized structure and function of the chloroplast membrane systems.
