Notes

Sn-glycerol-3-phosphate accumulates during starch catabolism by intact isolated chloroplasts from Chlamydomonas reinhardii in the dark. Further products detected mainly were 3-phosphoglyceric acid and triose phosphates with a ratio between 3-phosphoglyceric acid, sn-glycerol-3-phosphate and triose phosphates of 1.0:0.9:0.2. The production of sn-glycerol-3-phosphate by a plastidic glycerol-3-phosphate dehydrogenase provides a reasonable mechanism for regenerating reducing equivalents during continuous starch breakdown in the chloroplast of the alga C. reinhardii.
