In rats fed soybean phospholipid, concentration of serum cholesterol and apo A-I decreased and that of apo B (especially high-molecular-weight apo B) increased significantly compared to rats fed soybean oil. The reduction of serum apo A-I and cholesterol in rats fed soybean phospholipid appeared to be due to the decreased secretion from the liver as well as intestine, while the increase in the serum apo Bh being due to delated clearance from the circulation. Among the phospholipids tested, phosphatidyl-ethanolamine or its constituent base was the responsible for the alterations described above.
These results suggest that dietary phosphatidylethanolamine or ethanolamine have relevance to the regulation of serum lipoprotein metabolism.
