In poikilotherm animals--the frog Rana ridibunda, lizards Lacerta strigata, Eremias arguta, snake Natrix tesselata--high glycogen and glucose concentrations have been found not only in the liver, but also in muscles and especially in the brain. The content of glycogen in the brain of the reptiles investigated is 63.5--4.2 times higher, whereas that of glucose--6.9--39.5 times higher than in the brain of rats. The level of free fatty acids in the blood of frogs and snakes studied is the same as in rats, being 3.8 times higher in the blood of the lizards.
在变温动物——青蛙林蛙、蜥蜴条纹蜥蜴、快步麻蜥、蛇棋斑水游蛇——中，不仅在肝脏中发现了高浓度的糖原和葡萄糖，在肌肉中尤其是在大脑中也发现了高浓度的糖原和葡萄糖。所研究的爬行动物大脑中的糖原含量比大鼠大脑中的高63.5至4.2倍，而葡萄糖含量则高6.9至39.5倍。所研究的青蛙和蛇血液中的游离脂肪酸水平与大鼠相同，蜥蜴血液中的游离脂肪酸水平比大鼠高3.8倍。
