Abstract Oleic acid (C18∶1), a monounsaturated omega-9 fatty acid, is an important seed quality trait in peanut (Arachis hypogaea L.) because it provides enhanced fatty acid composition, a beneficial effect on human health, improved flavor, and increased shelf life for stored food products by delaying rancidity. Consequently, an emphasis has been placed on breeding peanuts with high levels of oleic acid and low levels of linoleic acid (C18∶2), a polyunsaturated, omega-6 fatty acid. Therefore, crosses were prepared between high oleic and normal peanut lines to develop segregating F2 populations. Total fatty acid composition and the ahFAD2B genotype were determined in the parents and progeny. The oleic to linoleic (O/L) ratio varied from 0.85 to 30.30 in the F2 progeny. Comparing the mean oleic acid values from the three genotypic classes (Ol2Ol2, Ol2ol2, and ol2ol2) in each population confirmed that the means were significantly different. Statistical analysis demonstrated that oleic acid was negatively correlated with linoleic (C18∶2) and palmitic acid (C16∶0), but was positively correlated with gadoleic (C20∶1) and lignoceric (C24∶0) fatty acids. This suggests that modifier genes may influence fatty acid composition. Principally, integration of genotyping and phenotyping data from segregating populations provided valuable insights on the genetic factors controlling total fatty acid composition.

Marine Oil

To evaluate how rapidly and to what extent a lipid emulsion rich in n-3 fatty acids could alter platelet function, six male juvenile African Green Monkeys (4-6 kg) were given a 6-hour IV continuous infusion of a 10% marine oil (MO) lipid emulsion (5 ml /kg/hr). Following a 21-day washout period, the same monkeys were given a similar infusion of a 10% soybean oil (SO) lipid emulsion (TRAVAMULSION®, Travenol Labs). Blood samples were collected pre-infusion, and at 6, 12, and 24 hours following initiation of infusion, upon which the following were measured: whole blood platelet aggregation and thromboxane B2 release following collagen activation, platelet count, and platelet total fatty acid composition (pre-infusion and 24 hrs only). Lipid Emulsion Fatty Acid Composition: mg/ml(% total F.A.) Both emulsions elicited comparable reductions in both platelet aggregation and thromboxane B2 release immediately following infusion (6 hr). Platelet aggregation response after MO was significantly less than that after SO at both 12 (pc.001) and 24 hrs (p<.001), and thromboxane B2 release was significantly less after MO vs SO at 24 hrs (p<.03). Platelet counts remained unchanged after both treatments. Platelet total fatty acid analyses revealed significant increases in % total F.A. for C20:5 [1.87(pre) vs 4.79(24hr); p<.005] and for C22:6 [1.09(pre) vs 3.15(24hr); p<.001] and significant decreases in % total F.A. for C18:2 [8.94(pre) vs 7.77(24hr); p<.05] and C20:4 [22.6(pre) vs 19.6(24hr) p<.05], following infusion of M0. Following infusion of SO, the % total F.A. change in C22:6 was the only one of significance [0.85(pre) vs 1.25(24hr); p<.05]. This was attributed to the C18:3 in the SO lipid emulsion. Whereas the IV infusion of an n-6 rich lipid emulsion has little effect upon platelet fatty acid composition and function, similar administration of an n-3 rich lipid emulsion markedly reduces platelet function and effects a significant increase in the n-3/n-6 fatty acid ratio of the platelets.
