The cell membrane is composed by a lipidic bilayer. Phospholipids are most likely found in the membrane of a eukaryotic cell.
<h3>MEMBRANE COMPOSITION</h3>
The cell membrane is composed of
- glucans incrusted in between.
The membrane is mostly composed of phospholipids.
<h3>PHOSPHOLIPIDS</h3>
Phospholipids are amphipathic molecules.
They have hydrophilic heads facing the exterior and the interior of the cells and hydrophobic tails that arrange against each other in the interlayer space.
Lipids can easily change places with other lipids by lateral diffusion in the same layer.
They can diffuse transversally to the other layer but not as easily as lateral diffusion.
There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.
Phospholipids are most likely found in the membrane of a eukaryotic cell.
