An experiment was conducted with Leghorn chicks to evaluate the effect of glucose or sucrose on liver and carcass glycogen. Phosphorylase a and synthase a were assayed to learn if glycogen cycle enzymes could be influenced by the early plane of nutrition. Both glucose and sucrose in drinking water increased liver and carcass glycogen in 3-day-old chicks. Groups given sucrose had more liver glycogen than groups given glucose after 5 days. Supplementary glucose given to fed chicks resulted in an increase in glycogen synthase a and a decrease in glycogen phosphorylase a at 4 days of age. By 6 days of age, differences in synthase activity between groups given sucrose or glucose were small. However, glucose solutions decreased phosphorylase a activity. The relationship between synthase a and phosphorylase a also partially regulates glycogen metabolism.
用来亨鸡雏鸡进行了一项实验，以评估葡萄糖或蔗糖对肝脏和胴体糖原的影响。测定了磷酸化酶a和合成酶a，以了解糖原循环酶是否会受到早期营养水平的影响。饮用水中的葡萄糖和蔗糖均增加了3日龄雏鸡的肝脏和胴体糖原。5天后，给予蔗糖的组比给予葡萄糖的组肝脏糖原更多。给喂食的雏鸡补充葡萄糖会导致4日龄时糖原合成酶a增加，糖原磷酸化酶a减少。到6日龄时，给予蔗糖或葡萄糖的组之间合成酶活性差异很小。然而，葡萄糖溶液降低了磷酸化酶a的活性。合成酶a和磷酸化酶a之间的关系也部分调节糖原代谢。
