对于新教材高二生物《实验一生物组织中的还原糖、脂肪、蛋白质的鉴定》中的有关斐林试剂和双缩脲试剂配制的问题(此实验在高中阶段是个定性实验),若按课本上那样准备和实验的话,其操作繁杂费时,且学生不易记住。我们在探索此实验时,统一采用了10%的硫酸铜和10%的氢氧化钠溶液来配制斐林试
For the new textbook, the sophomore organism “Examination of Reducing Sugars, Fats, and Proteins in Experimental Biological Tissues”, questions about the formulation of Firin reagents and biuret reagents (this experiment is a qualitative experiment in high school), if textbooks are Preparing and experimenting like that, its operation is time-consuming and difficult for students to remember. When we explored this experiment, we used 10% copper sulfate and 10% sodium hydroxide solution to formulate the Fielline test.
