What is the role of Glycoprotein and Glycolipid in Cell Membranes?
Notes from the video ‘H2 Biology Tuition | H1 Biology Tuition | Glycoprotein and Glycolipid in Cell Membranes’:
In this Biology tutorial, we would learn the role of glycoprotein and glycolipid in cell membranes.
Structure of Glycoprotein and Glycolipid
Glycolipids are lipids that are covalently bonded to carbohydrate molecules while glycoproteins are proteins that are covalently bonded to carbohydrate molecules.
Functions of Glycoprotein and Glycolipid
The diverse carbohydrate component allows for unique shapes which allow them to act as markers for cell-cell recognition to distinguish cells as self or non-self as the basis of the immune system.
Cell-cell recognition also results in cell adhesion, allowing cells to be attached to one another to form tissues and organs.
Glycolipids may act as receptors for certain bacterial toxins to bind to host cells, and glycolipids in the myelin sheath are used for electrical insulation of nerve cells.
