Which reagent is used to detect the presence of polysaccharides?

4 min read
According to biochemical research, the iodine test is the classic and most well-known method for detecting the presence of polysaccharides like starch. This simple colorimetric reaction relies on iodine-potassium iodide, commonly known as Lugol's solution, to produce a dramatic color change in the presence of certain complex carbohydrates. However, other reagents are also used depending on the specific type of carbohydrate and the analysis required.
