Three groups of 3 sheep were penned individually and provided with pelleted dried grass. In addition two of the groups received either dextrin or glucose via duodenal cannulae. The rate of in vitro lipogenesis, from acetate of glucose, in subcutaneous adipose tissue was significantly increased in the carbohydrate-infused sheep. The increase in lipogenesis in response to glucose infusion was much greater than that to dextrin infusion. The changes in lipogenesis induced by dextrin or glucose infusion were reflected in the specific activities of the various lipogenic enzymes examined. These results are discussed in relation to the capacity of the sheep small intestine to hydrolyse alpha-linked glucose polymer.
将三组三只绵羊单独圈养，并提供颗粒状干草。此外，其中两组通过十二指肠插管分别接受糊精或葡萄糖。碳水化合物注入组绵羊皮下脂肪组织中由葡萄糖乙酸盐生成脂肪的体外速率显著增加。对葡萄糖注入的脂肪生成增加远大于对糊精注入的增加。糊精或葡萄糖注入诱导的脂肪生成变化反映在所检测的各种脂肪生成酶的比活性上。结合绵羊小肠水解α-连接葡萄糖聚合物的能力对这些结果进行了讨论。
