A complex substance that, on hydrolysis, yields polyhydroxy aldehyde or ketone subunits is called
Correct answer: B. Carbohydrate
- A. Lipid
- B. Carbohydrate
- C. Protein
- D. All of these
Explanation
Carbohydrates are made of hydrocarbons; hence, on hydrolysis, they may yield polyhydroxy aldehyde or ketone subunits. Lipids are made of a glycerol backbone, two fatty acid tails, and a phosphate group. Proteins are polypeptides.
