Glycolipids - are lipids attached to a carbohydrate via a covalent bond that can facilitate cellular recognition. Cellular recognition allows the cell to differentiate between other types of cells.


Glycoproteins - are proteins attached to a carbohydrate via a peptide bond. Glycoproteins have various functions such as acting as a receptor to receive chemical signals, Another function is it's role in the immune system where it acts to protect the body.

Glycolipids are basically a lipid attached to a carbohydrate (glycogen as the name refers! By a glycosidic bonds that are doing in cell membranes helping in cellular recognition. Whereas, glycoproteins are a carbohydrate attached to the polypeptide chains of any proteins usually found in cell membrane as well as in the blood which as as receptors for chemical signals to bring about a certain response.
