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).
