Chicken, cholesterol

Serum triglyceride levels in chickens infected with all subgroup C viruses were increased. The greatest change was induced by RAV-7 with a mean of 1500 mg/dl after 45 days compared with a range of 68.2-90.5 mg/dl in uninfected chickens. Cholesterol levels decreased initially followed by a significant increase, 45 days posthatching. Marked hyperlipidemia was present only in RAV-7-infected chickens. 

When properly formulated, soy protein allows for significant cost savings, increased yields, reduced fat, increased protein, reduced cholesterol, reduced sodium and/or reduced calories while maintaining muscle tissue integrity. Applicable finished products include ham, roast beef, chicken, turkey, seafood and other whole muscle foods. Finished product characteristics given specific goals and guidelines are outlined as are new product opportunities.

In studying results from both chickens and man, Fisher et al. (67) concluded that pectin has a hypocholesterolemic effect only when fed with dietary cholesterol. On cholesterol-free diets, plasma cholesterol is not affected by dietary pectin. Subjects fed pectin with a cholesterol-containing diet had plasma cholesterol levels that were lower relative to those of subjects on the cholesterol control diet, but not relative to those of subjects on a cholesterol-free control diet.

HMG-CoA reductase, the enzyme that catalyses the formation of mevalonate [MVA, (2)] from HMG by an irreversible reaction that is considered rate-limiting with respect to the formation of cholesterol, has received much attention. Details of the purification of the enzyme from chicken liver and baker s yeast are available,15 and the solubilized enzyme from rat liver microsomes is readily and reversibly inactivated at temperatures below 19°C.16 Cold-inactivation is an uncommon phenomenon, and all the enzymes that have been found to exhibit this behaviour have been soluble proteins. Native HMG-CoA reductase is a particulate enzyme that is probably bound to protein or lipid of the microsomal membrane, although it is not known whether the solubilized enzyme contains a lipid component. Microsomal reductase is not cold-sensitive, and the cold-inactivation of the solubilized enzyme can be completely prevented by addition to the preparation of NADP+ or (more effectively) of NAD PH.17... 

Give those receptor sites phytosterols and the sites accept them as if they were cholesterol, thus blocking cholesterol itself. The trick, then, is to take concentrated phytosterols in tablet form at the beginning of a meal, especially meals containing animal foods that have cholesterol. Bear in mind that all animal foods have essentially the same amount of cholesterol whether they re lean or fatty in fact, chicken breast has more cholesterol than beef does. 

A chicken egg contains about 213 mg of cholesterol. Calculate how many moles of cholesterol this represents if the molecular mass of cholesterol is 386 amu. 

This class of lipid conjugates Is the most nonpolar yet Identified, a characteristic which Is often useful In pursuing the Identification of unknown metabolites. The first cholesterol ester of a xenobiotic was reported In 1976 for a saturated methoprene metabolite which contributed 15% of the total C-resldue In the liver of a chicken given a single oral dose of methoprene at 64 mg/kg (17). The tai-cyc lop ropy 1 fatty acids derived from cycloprate also form esters of cholesterol. Three such esters contributed 5% of the total residual radiocarbon In rat carcasses four days after a single oral dose of cycloprate at 21 mg/kg ( ). 

That many chemical substances are not soluble in sc carbon dioxide permits selective extraction.100 It is often used with foods, for which it eliminates the possibility of leaving toxic residues of solvents such as methylene chloride. It also avoids the hydrolysis that might occur when esters (for flavors or fragrances) are recovered by steam distillation. It has been used to extract the flavor from hops, the caffeine from coffee, fat and cholesterol from foods,101 pecan oil,102 lavender oil (for which hydrolysis of linalyl acetate could occur in steam distillation), 103 ginseng (from which it does not extract pesticide residues),104 ginger,105 microalgae,106 cooked chicken,107 ethanol from cider,108 and many others. One method used with aromas and con-... 

Biochemical alterations have been found in fragmented sarcoplasmic reticulum isolated from dystrophic human, mouse and chicken muscle. Alterations in calcium transport, ATP hydrolysis and phosphoenzyme formation have been reported. Some of these biochemical alterations in the dystrophic sarcoplasmic reticulum are suggested to be due to alterations of the lipid environment of these membranes it has been suggested that the cholesterol content of dystrophic sarcoplasmic reticulum is elevated [182-187]. 

Enjoy your eggs. This nearly perfect food once had a bad rap as a dangerous source of cholesterol, but nutritionists now understand that eggs are actually good for your heart and circulation, especially if you get them from farm-raised free-range chickens, and even more so if you eat eggs from flax-fed chickens, which inserts some brain-healthy Omega-3 into your diet.
