Am·a·dor·i re·ar·range·ment

a rearrangement that occurs in cross-linking reactions seen in collagen and in protein glycosylations; for example, conversion of N-glycosides of aldoses to N-glycosides of the corresponding ketoses.

This non-enzymatic process initially forms reversible early glycosylation products and later irreversible advanced glycosylation end-products (AGEs) via an Amadori rearrangement.
Undergoes an Amadori rearrangement, producing a ketoamine;
The aldehyde group of the glucose first forms a Schiff base with the NH2-terminal amino group, which then rearranges to a more stable amino ketone linkage by a spontaneous (nonenzymatic) reaction known as the Amadori rearrangement.
When glucose reacts with hemoglobin (Hb), the first products are Schiff bases that slowly undergo Amadori rearrangement to produce stable ketoamines (glycohemoglobin).
