Glutamine is an amino acid that has -CH₂-CH2-CO-NH₂ as its R group. The R group of the amino acid isoleucine is -CH2-CH-(CH3)2. If these amino acids were in a globular protein in aqueous solution, where would they most likely be? O Both glutamine and isoleucine would be in the interior and on the exterior of the globular protein. O Glutamine would be in the interior, and isoleucine would be on the exterior of the globular protein. O There isn't enough information O Both glutamine and isoleucine would be on the exterior of the globular protein. O Isoleucine would be in the interior, and glutamine would be on the exterior of the globular protein.
