The biosynthesis of human hemoglobin A1c. Slow glycosylation of hemoglobin in vivo.
Hemoglobin A1c, the most abundant minor hemoglobin component in human erythrocytes, is formed by the condensation of glucose with the N-terminal amino groups of the beta-chains of Hb A. The biosynthesis of this glycosylated hemoglobin was studied in vitro by incubating suspensions of reticulocytes and bone marrow cells with [3H]leucine or 59Fe-bound transferrin. In all experiments, the specific...
متن کاملMeasurement of Hemoglobin A1c
Evaluation of glycemia is used for the diagnosis and management of patients with diabetes. Glucose and hemoglobin A1c (HbA1c) provide complementary information and both are used to assess an individual’s glycemic status. The concentration of glucose in the blood indicates the subject’s glycemia at the time of blood sampling. However, blood glucose concentrations are modified by numerous factors...
متن کاملUnexpected hemoglobin A1c results.
A 52-year-old woman with a medical history of hepatitis B, hyperlipidemia, hypertension, anemia, and depression presented to the internal medicine clinic for a routine visit. Laboratory tests 3 months previously had revealed an impaired fasting glucose concentration of 5.9 mmol/L (106 mg/dL) [reference interval, 3.9 –5.6 mmol/L (70 –100 mg/dL)]. Therefore, a hemoglobin (Hb) A1c analysis was per...
متن کاملHemoglobin A1c: Clinical applications and analytical considerations
Diabetes Mellitus (DM) is the most common disorder of carbohydrate metabolism. Hyperglycemia is the common feature of DM. Hyperglycemia causes cardiovascular, renal, ocular, and peripheral nerve disorders in patients with diabetes. Glycemic regulation plays an essential role in controlling these complications. Thus, evaluation of the glycemic control status is crucial in the management of DM. H...
متن کاملNonenzymatic glycosylation of hemoglobin.
The incubation of dialyzed hemoglobin A with a number of phosphorylated glycolytic intermediates leads to the formation of covalent hemoglobin adducts that co-chromatograph with hemoglobin AIb. Phosphorylated hexoses (glucose-6-P, fructose-6-P, fructose-1,6-P2) and trioses (glyceraldelyde-3-P, dihydroxyacetone-P) containing a free aldehyde or ketone can glycosylate hemoglobin A nonenzymatically...
