Iodine test is used to detect:
Correct answer: D. Carbohydrates
- A. Fats
- B. Typhoid
- C. Malaria
- D. Carbohydrates
Explanation
The iodine test is a chemical test for the presence of starch, a type of carbohydrate. When iodine is added to a sample containing starch, it turns a blue-black color, indicating a positive result. This is because iodine interacts with the helical structure of amylose, a component of starch. The other options (fats, typhoid, and malaria) are unrelated to the iodine test: fats are a different class of biomolecules, and typhoid and malaria are diseases not detected by this test.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
