Which formula is a carbohydrate?
Correct answer: C. C3H6O3
- A. CH3CHO
- B. C2H5OH
- C. C3H6O3
- D. C15H31COOH
Explanation
Carbohydrates generally follow the formula Cn(H2O)m. Option C, C3H6O3, follows this formula (where n = 3 and m = 3), making it a carbohydrate. Option A, CH3CHO, is an aldehyde, not following the carbohydrate formula. Option B, C2H5OH, is ethanol, an alcohol. Option D, C15H31COOH, is a fatty acid, specifically palmitic acid, and does not fit the carbohydrate formula.

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.
