Question

How do the R groups of polar amino acids contribute to their ability to form hydrogen bonds?

Accepted Answer

They contain electronegative atoms that can form hydrogen bonds with water.

Answer

They have hydrophobic side chains that repel water.

Answer

They lack electronegative atoms, preventing hydrogen bonding.

Answer

They contain only carbon and hydrogen, which do not participate in hydrogen bonding.
