The effects of beef tallow and cocoa butter, two fats with a high stearic acid content (C18:0), on serum lipid and lipoprotein concentrations were compared with the effects of butter fat and olive oil in 10 middle-aged men. Liquid-formula diets containing 40% of the calories from the test fat were fed in random order for 3 wk each, with lipoprotein concentrations measured on the last five days....

I. Diets containing different proportions of skim milk and fat, either beef tallow or soyabean oil, supplemented with fat-soluble vitamins were given to 2-d-old pigs. Each fat source was used in three diets containing approximately 280, 350 and 420 g fat, and 260, 235 and 210 g protein/kg dry matter respectively. 2. The diets were given as a milk containing zoo g solids/l during a 26 d experime...

Dietary fat and calcium have been found to affect significantly the proliferative status of the mammary glands. Female mice (3-week-old C57BL/6J) were given either a low or high corn oil diet (3 or 30% by weight). One, 2, or 4 weeks after the dietary intervention the animals were given injections of [3H]thymidine and/or colchicine; 2 h later their thoracic mammary glands were removed and proces...

I . Tridodecyl glyceryl ether (I ,z,3-tridodecoxypropane) was prepared and purified for use as a lipid-soluble indicator of fat absorption. It was separated from other lipids present in samples of diet, digesta and faeces by thin-layer chromatography and determined by gasliquid chromatography. 2. In balance studies using rats which received a semi-purified diet containing beef tallow, 97-98 "/o...

Peroxisome proliferator-activated receptor delta promotes fatty acid catabolism and energy expenditure in skeletal muscle and adipose tissues. A ligand for PPARdelta is required to activate PPARdelta function. Polyunsaturated fatty acids are potential ligands for PPARdelta activation. The current experiment was designed to determine the potential for PUFA, particularly from dietary fish oil, to...

Biodiesel can substitute for conventional diesel fuel and contribute to the decarbonization of transportation sector. To improve biodiesel sustainability decrease production costs, low-grade fats such as non-edible animal must be used. Animal are mixed with tissues which removed before alcoholysis avoid contamination nitrogen phosphorus-containing compounds. was produced by methanolysis beef ta...
