Abstract/OtherAbstract:
|
The incorporation of phospholipids specifically labeled with glycerol-2(3)H and acyl-(14)C by whole cell tissues of developing soybean cotyledons (Glycine max L.) reveals that phosphatidylinositol, phosphatidylcholine, phosphatidylethanolamine, N-acylphosphatidylethanolamine, and phosphatidic acid can be metabolized to diglyceride. The diglyceride formed may be recylced into phospholipid or acylated to triglyceride. Diglyceride from phosphatidic acid and phosphatidylethanolamine is used readily in triglyceride biosynthesis compared to the other phospholipids. Incorporation of N-acylphosphatidylethanolamine having [9-10-(3)H(N)]oleic acid esterified at sn-3 in cotyledons shows rapid acyltransfer of (3)H into triglyceride and therefore N-acylphosphatidylethanolamine appears to participate in triglyceride biosynthesis as an acyl donor. These studies emphasize phospholipid metabolism in developing soybean cotyledons is a dynamic process which plays a key role in triglyceride formation. |
