DENDROLOGY

Detailed explanation-1: -Benedict’s solution is used to detect reducing sugars, typically monosaccharides or disacharides. It will show a positive result for reducing sugars such as glucose, fructose, lactose, maltose, galactose. It will show a negative result for non-reducing sugars such as sucrose, starch. Figure 1.

Detailed explanation-2: -It can be noted that Benedict’s test can also be used to check for the presence of glucose in a urine sample. Since this test detects any aldehydes and -hydroxy ketones and glucose is an aldose whose open-chain forms an aldehyde group, the test yields a positive result when glucose is present in the analyte.

Detailed explanation-3: -We can use a special reagent called Benedict’s solution to test for simple carbohydrates like glucose. Benedict’s solution is blue but, if simple carbohydrates are present, it will change colour – green/yellow if the amount is low and red if it is high.
