Diffusion properties of lipids pure and in seeds

, : Diffusion properties of lipids pure and in seeds. Journal of the American Oil Chemists' Society 54(11): 487-489

Diffusion constants of some fatty acids and triglycerides in pure form and also in seeds were measured at different temperatures in order to elucidate the motion and organization of triglyceride molecules in oils. The size of the oil storage cavity (droplet) in seeds was estimated to be 0.8 .mu. Temperature dependences of the proton T1 relaxation time in some samples were measured by pulsed NMR. From these measurements it is concluded that since activation energies for the relaxation mechanism, diffusion, is the same in seeds as in pure oils, 0.22 eV, the nature of the motion is similar.

Determinations were made using thin-layer chromatography. Total lipid contents of Hakuho and Kura Kata-wase peaches were 2.2-3.6% in the seeds and 0.1-0.2% in the endocarp. Neutral lipids were 92.8-95.0% of the total lipids in the seeds and 47.4-4...
