Question

Quizplus · Accepted Answer

Transmembrane segments of integral membrane proteins are typically composed of hydrophobic amino acids, allowing them to span the hydrophobic core of the lipid bilayer. While they can be amphipathic (having both hydrophobic and hydrophilic regions), this is not a defining characteristic of a transmembrane segment, which is primarily hydrophobic to match the environment of the membrane's interior.
