Cell membraneBy: María Paula Arenas SierraMedicine student. Semester 3
The cell membrane is the place pointed to by the action of drugs , so it is the
importance of their study.
In the study of this lipid bilayer ,
they have developed artificial
prototypes
The researches find that, with this cell membrane create more effective
drugs that acting on membrane proteins and understand the changes
that exist in diseased cells.

Phospholipids form the main structure of the membrane, give fluidity to the cell and allow the
displacement of this
The phospholipids have 4 movements, the least used (because
need energy) is the flip-flop that allows the membrane to be
regenerated
Cellular Regeneration can cause: physical changes in the cell and its organelles.

Student´s comment
This news is another proof of the progress of science, but keep in mind that everything in scientific development is good as long as it does not violate the normal laws of nature.
The peptoid to be a long molecule with one end water-loving and the other end fat-
loving, just like the lipid molecules in cell membrane.
In aqueous solution , this material becomes a
nanomembrane because the molecules spontaneously
crystallized
The nanomembrane can interact with particles such as
sodium, this particle involved in cell
signaling.

The peptoid has the ability to hold proteins with
different functions.

This is what appeals to the

Student´s comment
• This peptoid is very important because it give us the possibility of develop new prototypes of cell membrane that are larger and easier to manipulate in laboratory techniques.
Medical utility
Testing and development of more effective drugs that act on more specific parts of the membrane.
Medical utility
The study of the behavior of diseased cells.
Medical utility
These findings are closer to the ability to induce cell repair in cells
that can not repair itself
Medical utility
To create synthetic copies that we can control and whose objective is transported throughout the
body with specific target without being recognized by macrophages because they have a
cell membrane that the body identified
