File talk:Cell membrane detailed diagram en.svg
This image is inaccurate/misleading. Peripheral proteins are proteins usually attached by weak noncovalent bonds to protein emerged in bilayer, and even some of the more strongly attached proteins in this way are integral. Also, glycoproteins and glycolipids are usually not present in the inner layer/cytosol side of the membrane. The picture shows them on both sides. Sugars are attached to proteins inside Golgi apparatus, which is topologically equivalent to the outside of the cell (as Golgi generates exosomes). Though not quite impossible, these two mistakes on the pictures are inaccurate in that they do not represent a typical situation, and that is to put it mildly.
Peripheral vs Surface Proteins[edit]
I could be wrong, but I believe the Peripheral and Surface Protein labels in this image are the wrong way around. If you go to Cell Membrane the image above this one has the labels the other way around as well. From what I understand, peripheral proteins are not strongly attached to the plasma membrane and just sit very close to the surface, allowing them to break off easily.
