A newly synthesized polypeptide will ultimately be located within the phospholipid bilayer of the pla membrane. When this polypeptide folds to form its tertiary structure, the _____________ amino acid R-groups will most likely be facing outward.

Question

Quizplus · Accepted Answer

The phospholipid bilayer of a cell membrane is composed of hydrophobic tails facing inward and hydrophilic heads facing outward. Therefore, proteins that are embedded within the membrane must have hydrophobic amino acid R-groups facing outward to interact with the hydrophobic tails of the phospholipid bilayer. This allows the protein to be stably inserted within the membrane.
