Position specificity of the fatty acids in the phospholipids of the cotton plant variety 108-F

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.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.
