A protein was isolated from a plasma membrane by treatment with a detergent. An analysis of the amino acid sequence of the protein revealed a region of 30 contiguous non-polar amino acid residues. This suggests that the protein could be- 1) allosteric protein 2) an integral protein 3) a peripheral protein 4) a nonallosteric protein 5) a coenzyme. Explain your answer in detail.
