During 6 months the rats of different groups received isocaloric semi-synthetic diets that contained 18, 23, 28, 33, 38 and 43% protein (as regards caloricity). The most optimal magnitudes of the test characteristics of lipid metabolism--insignificant level of total lipids, total cholesterol and glycerides, the proportion of phosphatidylcholines and phosphatidylethanolamines in the content of phospholipids, the esterification ratio, the proportion of pre- beta- and beta-lipoproteins--were recorded in the groups given 18 and 23% protein in terms of caloricity. Further increase in the diet protein content produces a number of unfavourable shifts as regards lipid metabolism in white rats.
在6个月的时间里，不同组别的大鼠接受了等热量的半合成饮食，这些饮食所含蛋白质热量分别为18%、23%、28%、33%、38%和43%。在热量方面，给予18%和23%蛋白质的组中，脂质代谢测试特征的最适宜水平被记录下来，即总脂质、总胆固醇和甘油酯水平不显著，磷脂中磷脂酰胆碱和磷脂酰乙醇胺的比例、酯化率、前β-脂蛋白和β-脂蛋白的比例等。饮食中蛋白质含量的进一步增加会导致大白鼠脂质代谢出现一些不利变化。
