From chemistry, we know that each methylene $\left(?{\mathrm{CH}}_2?\right)$ group in a straight-chain hydrocarbon advances the chain length by about $0.13\mathrm{nm}$. And from studies of protein structure, we know that one turn of an $?$ helix includes 3.6 amino acid residues and extends the long axis of the helix by about 0.56 $\mathrm{nm}$. Use this information to answer the following: The protein bacteriorhodopsin has 248 amino acids and seven transmembrane segments. Approximately what portion of the amino acids are part of the transmembrane segments? Express your answer as an integer.
