Popis: 1. The composition of plasma esterified fatty acids (EFA) and their fractions [phospholipids (PL), triglycerides (TG); diglycerides (DG) and cholesterolesters, (CHE)] has been studied in arterial blood and in venous blood draining the isolated gastrocnemius dog muscle in situ. A-V differences of individual fatty acids (in mg-%) were calculated. 2. The arteriovenous differences of total EFA and PL were negative, mainly due to the release of saturated-fatty-acid-rich phospholipids containing palmitic and stearic acid. Positive arteriovenous differences have been found in the case of arachidonic acid in total EFA (in the non-phospholipid fraction), indicating an uptake of this acid probably from triglycerides. 3. The A-V differences of arachidonic acid and palmitoleic acid correlate with their content in arterial blood. The correlation for palmitic acid was inverse. 4. Plasma esterified fatty acids supply the muscle with the essential arachidonic acid while saturated-fatty-acid-rich phospholipids are carried away.
