The chemical composition of the peptidoglycan carrier bactoprenol is highly hydrophobic. Explain why this is necessary for bactroprenol to carry on its function.

 Bactoprenol is a hydrophobic C55 alcohol that bonds to peptidoglycan precursors. Bactoprenol transports peptidoglycan precursors across the cytoplasmic membrane by rendering them sufficiently hydrophobic to pass through the fatty acid tails of the membrane interior. Once in the periplasm, bactoprenol interacts with enzymes called transglycosylases that insert cell wall precursors into the growing point of the cell wall and catalyze glycosidic bond formation.
