Question 42

Matching

Indicate whether the following statements are TRUE or FALSE.If a statement is false, explain why it is false.

Premises:

Responses:

The "polypeptide backbone" refers to all atoms in a polypeptide chain, except for those that form the peptide bonds.

False

The relative distribution of polar and nonpolar amino acids in a folded protein is determined largely by hydrophobic interactions, which favor the clustering of nonpolar side chains in the interior.

True

The chemical properties of amino acid side chains include charged, uncharged polar, and nonpolar.

Generally, the total number of nonpolar amino acids has a greater effect on protein structure than the exact order of amino acids in a polypeptide chain.
