The cell is formed lipids,
proteins carbohydrates.

The lipids are ,
a special of lipid which one
a phosphate is bound
assigning electrical to this

phospholipids one electrically
extremity and long neutral
chain they organize
themselves two layers associated
molecules: hydrophilic portion
() of each faces outwards
contact with (a polar
too) of extracellular and
intracellular space the hydrophobic
(non polar) inwards isolated
the water. this type
membrane is of two
layers it also called bilipid
membrane.
