Which statement is true concerning the surface properties of this helix? This peptide has enough hydrophobic amino acid residues to be a transmembrane segment. The amino acid sequence intersperses pairs of hydrophilic residues between hydrophobic residues. This peptide forms a transmembrane barrel. The amino acids with the greatest hydropathy index cluster on one side of the helix. Choose the statements that describe how the helix orients in the tertiary structure of an integral membrane protein. The amphipathic helix interacts with the lipid bilayer along its hydrophobic surface, exposing its hydrophilic surface to the aqueous environment. The peptide entirely embeds in the lipid bilayer. A group of helices cluster with their polar surfaces in contact with one another and their hydrophobic surfaces facing the lipid bilayer. The threonine residues act as membrane interface anchors, interacting with the lipid bilayer and the aqueous environment. Which statement is true concerning the surface properties of this helix?
