Membrane phospholipids have
structural function, they the bilipid
membrane constitutes the cell
itself.

Membrane proteins several
specialized functions. of them are
for substances to through
the membrane, are receptors
and of information, others
enzymes, others are identifiers
(cellular labels) there are still
that participate in adhesion
complexes between or between the
surface of the and
the cytosketeleton.

carbohydrates, associated to
or to lipids, found in the
surface of the membrane and
they in general labeling
for recognition of cell by other
and substances (for , they
differentiate red cells in relation
