The ratio of saturated to unsaturated fatty acids in maize kernels strongly impacts human and livestock health, but is a complex trait that is difficult to select based on phenotype. Map-based cloning of quantitative trait loci (QTL) is a powerful but time-consuming method for the dissection of
To determine the mechanisms whereby diets differing widely in fatty acid composition affect plasma LDL cholesterol and apolipoprotein B concentrations, LDL kinetics and receptor- and nonreceptor-mediated LDL catabolism were investigated in 27 cynomolgus monkeys fed diets containing 0.05 mg
In order to examine the qualitative effect of different fats and specific fatty acids on plasma lipids and lipoprotein metabolism, six low fat, cholesterol-free diets were fed to young male hamsters (10/group) for a 4-week period. Fat blends were formulated with coconut oil, palm oil, soybean oil,
An experiment was conducted to evaluate the effects of dietary corn oil (CO) and commercial free fatty acids on the fatty acid composition of blood plasma and egg yolk lipids and on the reproductive performance of Japanese quail. When quail were fed a semi-purified low-fat basal mix, the
There have been few studies on the effect of cottonseed oil (CSO), one of the most commonly used vegetable oils in the United States, on indices of lipid status either in the rat or in any other species. Previous studies with rats have focused on the effect of CSO, versus that of other vegetable
The comparative effects of high-fat diets (20%, w/w) on eicosanoid synthesis during mammary tumor promotion in 7,12-dimethylbenz(a)anthracene (DMBA)-induced rats were studied using diets containing 20% primrose oil (PO), 20% menhaden oil (MO) or 20% corn oil (CO). Sprague-Dawley rats fed the PO or
The effects of fractions isolated from thermally oxidized corn oil or olive oil on the metabolic activity of heart endothelial and muscle cells were studied. Rat heart cells in culture, exposed to thermally oxidized fat components, took up more exogenous 1-14C-palmitic acid and incorporated more of
This study was conducted to evaluate the toxic effects and potency of 2-dodecylcyclobutanone (2-dDCB), a unique compound derived from palmitic acid via irradiation. In a series of assays of bacterial reverse-mutation, in vitro chromosomal aberration, and in vivo micronucleus, negative responses were
3H-palmitic acid and 14C-tripalmitate dissolved in 1.0 g indian corn oil/kg body weight were administered to 29 patients with chronic pancreatitis and 25 control subjects. For the following 8 h 3H and 14C radioactivity in serum lipids and 14CO2 in expired air were measured at 2-hour intervals.
To assess the influence of dietary fat composition on the contribution of dietary myristic and palmitic acid to total fat oxidation and energy production, eight healthy men consumed diets containing 40% of total energy as fat, largely as either butter, tallow or corn oil, for 11 days. On days 8 and
This manuscript describes changes in plasma lipid profiles and parameters of oxidative status in the plasma and liver of rats fed 5 different fatty acids: 95% eicosapentaenoic acid, 92% docosahexaenoic acid (DHA), corn oil (n-6), 1-mono-(carboxymethylthio)-tetradecane (CMTTD) and palmitic acid
The free sterols, the sterol esters and the sterol glycosides of the raw soya and corn oils as well as those of the technical lecithin and the deodorizer distillated of the latter oils were isolated by preparative TLC. The composition of each of the isolated sterol derivatives was determined by GLC
When rats were fed diets containing 10% corn oil for 2 weeks, alpha-glycerophosphate acyltransferase and diacylglycerol acyltransferase levels were reduced to 75% of that of controls fed a 0.5% corn oil diet, while glucose-6-phosphate dehydrogenase, malic enzyme and acetyl-Coa carboxylase levels
The comparative bioavailability of cocoa butter (a predominantly saturated fat) and corn oil (a predominantly unsaturated fat) was determined in male Sprague-Dawley rats by analysis of total fecal lipids following ad libitum feeding of purified diets containing 5, 10 and 20% cocoa butter or corn oil
