Cell membrane

hey!

Cholestrol

a steroid imbedded into the cell membrane. Cholesterol helps regulate fluidity in the cell membrane

Glycolipid

Lipids that have a carbohydrate attached to it by glycosidic linkages. They help with cell energy, cell membrane stability, and cell recognition

Glycoprotein

Proteins that have a sugar chain attached to it. They help with signaling and immune response

Receptor Proteins

These allow cells to communicate with the environment. Hormones and neurotransmitters will bind to these proteins because they cannot pass the cell membrane on their own. These are specific.

Integral Proteins

These are proteins that are embedded in the cell membrane. They help pass materials across the membrane and send signals to the cell

Peripheral Proteins

These are proteins found on either surface of the cell membrane. They help mostly with signaling and structural support.

Surface Proteins

These are proteins found only on the outside of the cell membrane. These help with cell recognition. Surface proteins are a type of peripheral protein.

Carrier Protein

These are proteins that have a channel spanning through the cell membrane. These are more specific than protein channels and must change shape to let molecules pass.

Gap Junctions

These are channels that connect the cytoplasm of adjacent cells through the cell membrane using membrane proteins to form a channel.
