Question

you recently identified a novel protein that contains several membrane - spanning domains. you would predict that the amino acids embedded in the membrane would have ________ side groups. multiple choice nonpolar positively charged polar uncharged negatively charged

Explanation:

Cell membranes are composed of a lipid - bilayer which is hydrophobic in the interior. Amino acids embedded in the membrane need to interact favorably with the hydrophobic environment of the lipid - bilayer. Nonpolar side groups are hydrophobic and can interact well with the lipid - bilayer, while polar (charged or uncharged) side groups are hydrophilic and would not be stable in the hydrophobic interior of the membrane.

Answer:

nonpolar
