Question

the chemical formulas for two amino acids are shown below. which of the following statements is true regarding these two amino acids? select all that apply. valine isoleucine the r groups of these amino acids are likely to be soluble in water. the r groups of these amino acids contain nonpolar covalent bonds. the r groups of these amino acids contain polar covalent bonds. the r groups of these amino acids can act as an acid ( donate h+)

Explanation:

Valine and isoleucine are non - polar amino acids. Their R - groups consist of hydrocarbon chains which have nonpolar covalent bonds. Nonpolar substances are not soluble in water and do not donate H+ easily as they lack functional groups that can ionize.

Answer:

The R groups of these amino acids contain nonpolar covalent bonds.
