Understanding the Answer
Let's break down why this is correct
Answer
Alkaline copper solution reacts with proteins to form a colored complex, so it is a test for proteins. Benedict’s reagent works in the opposite way: it reacts with reducing sugars and produces a color change. The reagent is specifically used to detect the presence of reducing sugars such as glucose. In practice, a sample is boiled with Benedict’s reagent; a bright orange‑red precipitate indicates sugars are present. Thus, the analogy is: Benedict’s reagent : reducing sugars detection.
Detailed Explanation
Benedict's reagent is a test that turns orange to red when it meets sugars that can give electrons to copper ions. Other options are incorrect because Some people think Benedict's reagent works with fats because fats are also molecules; DNA and RNA are nucleic acids that do not give electrons to copper ions in this test.
