amphipathic molecule

because in a bilayer you have all the hydrophilic heads at the exterior and the hydrophobic tails together on the inside. In a monolayer, you have the hydrophilic heads on one side and the hydrophobic tails on the other, so one of the sides ...

Cell Membranes

... transport, and about lysosomes. First of all, the only "holes" that are present in the cell membrane are ion channels, which have a tiny hydrophilic channel in the center that only allows the passage of a particular ion. Other polar molecules pass through other passage proteins (pumps/permeases). ...
