“生物组织中还原糖的鉴定”是一个比较简单的验证性实验。在实验过程中,如果按照课本介绍的方法操作,既不易观察到预期现象,又浪费实验材料和时间。另外,我们在实验过程中还发现,课本对某些实验现象和步骤的描述有失偏颇。为此,我们做了一些探索实验。现将探索过程和结果汇报如下(所做各项实验均重复3次以上):1 苹果组织样液和斐林试剂混匀后不呈蓝色,而呈绿色 “Identification of reducing sugars in biological tissues ” is a relatively simple confirmatory experiment. During the experiment, if we follow the method introduced in the textbook, it is not easy to observe the expected phenomenon, but also to waste the experimental materials and time. In addition, we also found during the experiment, the textbook for some of the experimental phenomena and steps described biased. To this end, we did some exploratory experiments. Now the exploration process and the results reported as follows (all experiments are repeated more than 3 times): 1 Apple tissue sample and Feilin reagent after mixing is not blue, but green
