[Phospholipid transport between subcellular membranes and blood lipoproteins and the effect of nutrition on these processes].

Experiments on rats (both in vivo and in vitro) were made to examine phospholipid transport between liver microsomes and mitochondria, microsomes and high density lipoproteins of the blood, as well as to assess the effect of nutrition on the processes under consideration. Phospholipid transport from liver microsomes to blood high density lipids under the in-vitro conditions is effected without special intermediaries. Supplementation of the incubation medium with lipid-carrying proteins from the liver speeds up phospholipid transport to blood lipoproteins. In this case, bilateral exchange of phospholipids takes place. The diets that are imbalanced as regards the content of carbohydrates and fat alter the intensity of phospholipid transport between liver microsomes and mitochondria. Phospholipid transport from cell membranes to high density proteins of the blood does not seem likely to depend on the alimentary factor.
