<prompt> The transmembrane region of protein is likely to have:A stretch of hydrophilic amino acidsA stretch of hydrophobic amino acidsA disulphide loopAlternating hydrophilic and hydrophobic amino acids  <response>: Ans. b A stretch of hydrophobic amino acidsRef: Ganong, 25th edp.Integral membrane proteins are also called as Transmembrane proteins because they are present in both inside and outside of membrane. They have both hydrophilic and hydrophobic regions AmphipathicHydrophobic region is present inside and hydrophilic region is present at the ends of bilayer
