Glycans are polysaccharides. Usually,this word is used to refer to the carbohydrate moiety of a glycoprotein. There are 2 types: O-linked and N-linked. O-glycans consist of N-acetyl galactosamine, galactose, and neuraminic acid. N-glycans consist of N-acetylglucosamine, fructose, mannose, galactose, and neuraminic acid. N-glycans are derived from a 14-sugar unit consisting of 14 residues (3 glucose, 9 mannose, and 2 N-acetylglucosamine). O-glycans, on the other hand, have one sugar added at a time. Examples of O-linked glycoproteins are: Polysaccharides (sometimes called glycans) are relatively complex carbohydrates. ...

Most glycoproteins are N-linked and have 5-15 sugar residues. O-linked glycoproteins have 1-4 sugar residues.
