The fatty acid composition of triglyceride and phospholipids in developing soybean cotyledons (Glycine max L., var. "Harosoy 63") was analyzed at several stages of growth between 30 and 70 days after flowering. Changes observed in fatty acid composition within each lipid class were related to the levels of lipid molecular species present in the oil. Thirteen molecular species of triglyceride were identified in developing cotyledons, however three of these groups: trilinolenic, dilinolenic-monolinoleic, and linolenic-linoleic-oleic triglycerides, were not found in the mature seed. In immature cotyledons, trioleic and trilinoleic triglycerides accounted for 50% of the structures found; the level of these molecules decreased to 24.9% in the mature seed. The dilinoleic-monolinolenic triglycerides increased from 0.4 to 23.4% during cotyledon development. Changes in triglyceride composition were compared to the levels of molecular species for each phospholipid class. Dilinoleic and monosaturated monolinoleic phospholipid species were dominant in all phospholipid classes throughout development. |
