Question

Consider statements about human nutrition: 1. Proteins are made of amino acids. 2. Carbohydrates are made of fatty acids. 3. Fats are made of glycerol and fatty acids. Which are correct?

A. 2 and 3 only

B. 1, 2 and 3

C. 1 and 2 only

D. 1 and 3 only

Answer: Option D

Solution (By JKSSB Mock Tests)

Proteins are complex macromolecules composed of long chains of amino acids linked by peptide bonds. Fats (triglycerides) are lipids composed of one glycerol molecule esterified to three fatty acid chains. Carbohydrates are composed of simple sugars (monosaccharides) like glucose, not fatty acids. Thus, statements 1 and 3 are correct, while statement 2 is false.
