WebbThe properties of the side chain determine an amino acid’s chemical behavior (that is, whether it is considered acidic, basic, polar, or nonpolar). For example, amino acids such as valine and leucine are nonpolar and hydrophobic, while amino acids like serine and glutamine have hydrophilic side chains and are polar. WebbThe only polar amino acids found completely buried are the two His (proximal and distal) found at the active site of dioxygen binding.
