Studies on sojabean Phosphatide. III. Studies on kephalin

SUZUKl and NISHIMOTO（1930）separated a series of kephalins from the sojahean which yjelded, on hydrolysis,only β-glycerophosphoric acid anj fatty acids.The fatty acids consisted of about 50％stearic acid and a mixtures of approxjmately equal parts of linoleic and linolenic acids. 0n the otherhand, HILDITCH and PEDELTY（1937）investigated the component acids of the alcollol-lnsoluble fraction（kepnalin）of sojabean phosphatides,and showed that the fatty acid consisted of palmitic acid 11.7％,stearlc acid 4.00％ arachidic acid 1.4％,hexadecenoic acid 8.6％,oleic acid 5.5％,linoleic acid 63.3％,linolcnic acid －％ and C_20－unsaturated acid 5.5％. As these two results showed much difference, the writer newly investigated the sojabean phosphatide and obtained the following results：...
