Studies on the Lipid Metabolism of Soybean during its Germination


Abstract
The Merit variety of soybean (Glycine max L.), harvested in 1971 was germinated in the dark at 21¡­25¡É for days. The soybean sprouts were divided into cotyledons and seedling axis (=hypocotlyplus root) and subjected to the determination of dry weight, crude fat content and lipid components (esterified sterols, triglycerides, free fatty acids free sterols and phospholipids) at two-day intervals during the germination periods.
The results are summarized as follows:
1) During the germination period, the dry weight and crude fat content in cotyledons decreased continuously, but the dry weight seedling axis increased continuously and crude fat content remained almost constent.
2) The triglyceride content in crude fat from cotyledons decreased and free fatty acid content increased continuously, but triglyceride content in crude fat from seedling axis showed no change until 6th day and increased slightly after 8th day, and free fatty acid content showed increase after 4th day and decrease after 6th day. Phospholipids, free and esterified sterols content in cotyledons increased continuously, but their content in seedling axis remained unchanged.
