under prolonged diabetic conditions, hba1c is produced from normal hemoglobin (hba0) through a non-enzymatic glycosylation or glycation, a process which enhances the hemoglobin susceptibility to be auto-oxidized to methemoglobin (methb). here we are reporting that the non-enzymatic reaction between fructose and methb (methb fructation) induces significant changes in the globin structure and deg...
