Glycosylation is a biochemical process where a glycan attaches to a protein, a lipid, or other organic molecule, especially through the catalytic action of certain enzymes.
Glycosylation is the reaction in which a carbohydrate, i.e. a glycosyl donor, is attached to a hydroxyl or other functional group of another molecule in order to form a glycoconjugate. In biology, glycosylation usually refers to an enzyme-catalysed reaction, whereas glycation may refer to a non-enzymatic reaction.
