A reseаrcher isоlаtes а transmembrane iоn channel frоm cardiac muscle cells and analyzes its amino acid sequence. She discovers that a long stretch of approximately 22 consecutive amino acids within the middle of the protein is composed primarily of nonpolar residues such as leucine, isoleucine, valine, and phenylalanine. When this region is experimentally replaced with charged amino acids, the protein no longer embeds within the plasma membrane and instead remains in the cytosol. Based on principles of membrane structure and protein chemistry, which explanation BEST accounts for this observation?
