Glycoproteins are components of the plasma membrane. State two functions of these molecules. Plz help! :lol:

It's a good idea first to find out about the fuctions of the various proteins in the cell membrane; refer to Campbell, its quite clear from there.

I think they play a role is cell recognition. Blood typing etc.

a few of roles of glycoproteins:
- cell to cell binding. A hepatocyte will never bind to any other cell than another hepatocyte for example.
- deposits of cations. usually glycoproteins are sulfatated or acetylated
- protection of the cell from enzymes.
- cellular identity-blood types, as it has been said. The A and B antigene form from the 0 antigene, and they are all glycoproteins

And many more...
