Which statement best describes the R-groups or side chains of amino acids?

The chemical behavior of an amino acid is always determined by the reactivity of its R-group.

  

The reactivity of side chains arises from the presence of the amino functional group NH3.

  

The nature of side chains determines how soluble each amino acid is in water.

  

The polarity of each amino acid is determined by the placement of COOH in each side chain.
