Proteins are biological molecules constructed of amino acids

Proteins are biological molecules constructed of amino acids linked together by peptide bonds and properly folded, as shown below. Which condition (circle) [A B or C] has the greatest entropy?

Solution

Answer: A has highest entropy.

Entropy is the measurement of randomness of a system. Amino acids in free form carry highest entropy.

Protein C has the least entropy. the folding of a protein is accompanied by a decrease in system entropy
