Which of the Following is a Property Common to Globular

Question

Which of the following is a property common to globular proteins?
A)They are soluble in water.
B)They are roughly linear in structure.
C)They fold so that the hydrophilic amino acids are in the interior of the molecule.
D)The hydrophobic side chains are exposed to the surrounding water.

Accepted Answer

Globular proteins are typically water-soluble due to their folded, compact structure that allows hydrophilic amino acid residues to be on the exterior surface in contact with the surrounding water.

Answer: C 
 Globular proteins are characterized by a compact, ball-like structure that typically forms so that the hydrophilic amino acid residues are on the interior of the molecule, shielded from the surrounding water. This allows the hydrophobic amino acid residues to be on the exterior surface of the molecule in contact with the surrounding water.
