چکیده انگلیسی
The ooplasm of mature oocytes of the polychaete Neanthes arenaceodentata is characteristically filled with yolk platelets. A major component of these structures is lipovitellin, which provides energy and materials required by newly hatched larvae. The lipovitellin isolated and purified from the fertilized eggs of this polychaete was a high-density lipoprotein composed of protein (57%), lipid (42%) and carbohydrate (1%). The lipid component included phospholipids (92% of lipid), triacylglycerol (3% of lipid) and cholesterol (3% of lipid), while sodium dodecyl sulfate-gel electrophoresis showed the major protein component was a 120-kDa peptide. Microscopically, mature oocytes were present in the coelom along with phagocytic eleocytes. The presence of muscle fragments and oil droplets in eleocytes suggests that eleocytes play an important role in providing the protein and lipid needed for the assembly of lipovitellin in the oocytes.
