Comparative studies have been made in the specific activity of sorbitol dehydrogenase, glucose-6-phosphate and alcohol dehydrogenases in the cytoplasm from the liver of wild and domestic ducks, hen and pheasant. High activity of all the three enzymes was found in ducks indicating the effective sorbitol (polyol) metabolism of glucose. The activity of glucose-6-phosphate dehydrogenase is an order lower as compared with the activity of sorbitol and alcohol dehydrogenases in the cytoplasm of hen liver. The same relationship was found for the activity of sorbitol dehydrogenase in the cytoplasm of pheasant liver.
对野鸭、家鸭、母鸡和野鸡肝脏细胞质中山梨醇脱氢酶、葡萄糖-6-磷酸脱氢酶和乙醇脱氢酶的比活性进行了比较研究。在鸭中发现这三种酶的活性都很高，表明葡萄糖的山梨醇（多元醇）代谢有效。母鸡肝脏细胞质中葡萄糖-6-磷酸脱氢酶的活性比山梨醇脱氢酶和乙醇脱氢酶的活性低一个数量级。在野鸡肝脏细胞质中，山梨醇脱氢酶的活性也发现了同样的关系。
