Question 5

Properties of a Non-Polar Amino Acid?

Answer 5

Hydrophobic with no charge. Often tucked away inside the protein core if the protein is soluble.

Question 6

Properties of Polar Amino Acids?

Answer 6

Uncharged but can participate in hydrogen bonding through atoms such as oxygen and nitrogen. Can produce hydrogen bonds with water or other polar groups.
