The relationship between dietary fat composition and plasma cholesterol esterification
1. Cholesterol esterscation has been studied in the plasma of subjects on diets rich in saturated or polyunsaturated fat. 2. The diet rich in polyunsaturated fat was associated with lower rates of plasma cholesterol esterification in vitro. The data suggest that there was a reduction of plasma lecithin-cholesterol acyltransferase activity as well as decreased ability of the lipoprotein substrat...
متن کاملCholesterol esterification in rabbit plasma.
1. When [4-(14)C]cholesterol, attached to beta-globulin or dispersed with Tween 20, was incubated with fresh rabbit (New Zealand albino females) plasma, 30-47% esterification was observed. The optimum pH was 6.8. This esterification was accomplished by the transfer of fatty acids from the C-2 position of lecithin (phosphatidylcholine) to cholesterol. 2. There was no evidence that triglycerides ...
متن کاملRole of the plasma membrane in cholesterol esterification in rat hepatoma cells.
The source of the cholesterol used for ester synthesis by cultured rat hepatoma cells was examined. The activities synthesizing and esterifying cholesterol co-distributed with RNA at a high buoyant density, presumably in the rough endoplasmic reticulum (RER). Cholesterol mass was undetectable in the RER, and the transfer of cholesterol synthesized in the RER to the cell surface was more than 10...
متن کاملEffects of dietary cholesterol and fatty acids on plasma cholesterol level and hepatic lipoprotein metabolism.
The effects of dietary cholesterol and fatty acids on the plasma cholesterol level and rates of very low density lipoprotein (VLDL) cholesterol secretion and low density lipoprotein (LDL) transport through LDL receptors in the liver of the hamster were investigated. Increases of plasma VLDL- and LDL-cholesterol levels and VLDL-cholesterol secretion from hepatocytes were observed in animals fed ...
متن کاملDietary protein level and performance of growing Baladi kids
A study was conducted to evaluate the effect of feeding different levels of protein to black Baladi breed kids. Weanling Baladi kids (n=18; 75 to 90 days old) were selected and individually housed at our experimental farm. Kids were divided randomly to one of the three treatments for 12 weeks. The three dietary treatments were: T1: control ration, formulated according to NRC to cover the protei...
