Certain side chains (R groups)in amino acids are nonpolar.In the structure of a protein,nonpolar groups are generally found
A)on the interior of the protein structure, shielded from interaction with water molecules.
B)on the exterior of the protein structure, shielded from interaction with water molecules.
C)on the interior of the protein structure, maximizing their interaction with water molecules.
D)on the exterior of the protein structure, maximizing their interaction with water molecules.

Question

Quizplus · Accepted Answer

Nonpolar groups are hydrophobic, meaning they interact poorly with water molecules. Therefore, they are typically found on the interior of a protein structure, where they can be shielded from interaction with water. This arrangement helps to stabilize the protein's structure.
