Summary
It has been shown by enzymatic hydrolysis with phospholipase A that it is mainly unsaturated fatty acids that are esterified in positions of the PC, PE, and PI molecules (93.2, 86.2, and 76.8%, respectively), which is normal for phospholipids.
From the results on the position distribution of the fatty acids we have calculated the possible molecular compositions of the PCs, PEs, and PIs.
