EFFECT OF DIETARY FAT ON LIPID COMPOSITIONS AND THE ACTIVITY OF CYTOCHROME OXIDASE OF CARDIAC MITOCHONDRIA FROM GUINEA PIGS / 营养学报

ABSTRACT

Effect of 10% lard diet on lipid compositions and the activity of cyto-chrome oxidase of cardiac mitochondria from guinea pigs was observed. The results showed that after feeding the diet for 50 days, the activity of cyto-chrome oxidase of the experimental animals tended to be lowered; the total cholesterol content was increased; in contrast, the total phospholipid content was decreased. As a result, the molar ratio of total cholesterol to total phospholipid was significantly raised (P
