This modification was of a nonpolar nature, did not affect the overall charge of the Hb and caused its aggregation in aqueous solution. After normal concentrations of glucose and insulin were reestablished, this modification slowly disappeared. Hemoglobin from normal erythrocytes incubated in vitro with high concentrations of insulin showed similar behavior. © 1991.Glycated hemoglobinHyperinsulinismHypoglycemia
