TYPE OF PROTEIN IN CELL
9. they are found on the outside surface of cells and are
bound either to proteins =forming glycoproteins
bound to lipids =forming glycolipids.
These carbohydrate chains may consist of 2-60
monosaccharide units and can be either straight or
10. Along with membrane proteins, these carbohydrates form
distinctive cellular markers, that allow cells to recognize each
These markers are very important in the immune system.
