Lipid compounds are gaining increasing attention due to a wide range of applications in the food industry. Particularly, supercritical carbon dioxide (SCCO2) is being successfully employed as a green solvent in the extraction and fractionation of nonpolar lipids. Knowledge of the solubility of pure lipid-type substances and their mixtures in SCCO2 is essential for evaluating the viability of su...

Six grossly obese patients were fed 5000 calorie diets for 4 wk. During one period of 2 wk, the calories were consumed over 4 hr (gorging) and during the other 2 wk, the dietary intake was spread over 20 hr (nibbling). Each of these periods followed a low caloric intake which lasted at least 10 days. Three male patients (group I) were studied at or near their maximal weight and three females (g...

For many years it has been recognized that particulate bodies within cells capable of carrying out energy transductions contain large quantities of lipids which include significant amounts of phosphatides, glycolipids, quinones, pigments and certain lipid soluble vitamins. A great deal of conjecture has been written concerning the possible role of lipids, especially those with amphipathic prope...

Only a few land-animal fats have been studied in detail so far with respect to their fatty acid composition and the pattern of glyceride molecules. Among those whose fatty acid compositions are available are lion and cat (Hilditch, Sime & Maddison, 1942; Gunstone & Russell, 1954), puma (Giral, 1945), tiger (Pathak & Agarwal, 1952; Gunstone, 1955), sacred baboon, Ceylon sloth bear (Hilditch et a...

In a preliminary study of lipogenesis in vitro in livers of diabetic rats, it was observed that insulin lack did not affect the incorporation of fructoseJ4C into total lipid even though it markedly reduced fatty acid synthesis.1 Since the difference in 1% content between total lipid and fatty acid could represent 14C label in glyceride-glycerol, this finding suggested that glyceride-glycerol sy...

Nanavati"and Sukh Dev National Chemical Laboratory, Poona, India (Received in 1K 25 January 1973; accepted for publication 1 Wbruary 1973) In connection with pharmacological properties ascribed to the seeds of Celastrus paniculatus Willd. (Hindi: Malkanguni), a plant mentioned in old Indian medical literature, the composition o...

Cultures of the phytoflagellate Eugfena gracitis were grown at light intensities varying from 120 to 610 footcandles. With increasing light intensity, the content of chlorophyll and of total lipids declined, whereas the percentage of 4,7, 10,13-hexadecatetraenoic acid and of ar-linolenic acid rose sharply. The increased content of the two polyunsaturated fatty acids was even more pronounced in ...

It was demonstrated by Barrett, Best & Ridout (1938) that the administration of APP to fasting mice caused rapid mobilization of lipid from the depots with an accumulation of lipid in the liver. Stetten & Salcedo (1944) demonstrated this effect in rats. The results of the present study in mice and rats support and extend these findings. The glyceride fraction was principally affected in the mob...

This study was conducted to investigate the effects of lecithin, mono-glyceride and mono-diglyceride on apparent total tract and ileal nutrient digestibilities in nursery pigs. Twenty [(Landrace x Yorkshire) x Duroc] barrows were surgically fitted with simple T-cannulas. Dietary treatments included 1) CON (basal diet: soy oil), 2) LO (lecithin 0.5%), 3) MO (mono-glyceride 0.5%), 4) MG (mono-gly...
