The epidermis. It's the first layer of skin.
The cell plasma membrane is composed of a phospholipid bilayer structure in which the hydrophobic tails of each phospholipid face inwards forming a hydrophobic core. The core restricts movement of hydrophilic substances across the membrane by repelling them. Hence the peptidoglycan precursors must be sufficiently hydrophobic in order to bypass the hydrophobic core of the bilayer and leave the cell to reach the cell wall.
