What is Glycophorin?
A Glycophorin is a sialoglycoprotein of the membrane of a red blood cell. It is a membrane-spanning protein and carries sugar molecules. It is heavily glycosylated (60%). Glycophorins are rich in sialic acid, which gives the red blood cells a very hydrophilic-charged coat. This enables them to circulate without adhering to other cells or vessel walls.
What is spectrin?
Spectrin is a cytoskeletal protein that lines the intracellular side of the plasma membrane in eukaryotic cells.
