Glycation is the result of typically covalent bonding of a protein with a sugar molecule, such as fructose or glucose, without the controlling action of an enzyme. Glucose reacts with proteins through the formation of a Schiff base between the aldehyde group of glucose and the primary amines of lysine and the N-terminus of the protein.
