Abstract

Rats, chicks, and pigs were fed diets containing fructose or glucose. Plasma triglyceride levels were elevated in rats but not in chicks or pigs fed diets containing fructose. The rate of fatty acid synthesis in rat liver but not in chick liver was elevated when fructose-containing diets were fed. Conversely, the rate of fatty acid synthesis in rat adipose tissue but not in pig adipose tissue tended to be depressed when fructose-containing diets were fed. These results indicate that there are species-specific as well as organ-specific metabolic responses to various dietary carbohydrates.

摘要

给大鼠、小鸡和猪喂食含果糖或葡萄糖的日粮。喂食含果糖日粮的大鼠血浆甘油三酯水平升高，但喂食相同日粮的小鸡和猪血浆甘油三酯水平未升高。喂食含果糖日粮时，大鼠肝脏中脂肪酸合成速率升高，而小鸡肝脏中未升高。相反，喂食含果糖日粮时，大鼠脂肪组织中脂肪酸合成速率趋于降低，而猪脂肪组织中未出现此现象。这些结果表明，不同物种以及同一物种的不同器官对各种膳食碳水化合物的代谢反应存在特异性。
