- 34.The production of glycogen within our liver and skeletal muscle cells requires what type of reaction? Dehydration Hydrolysis Ionic Dissociation. Separating Glycated Hb From Normal Hb (Integrates with Chapters 5and 6.) Human hemoglobin can react with sugars in the blood(usually glucose) to form covalent adducts. The a-amino groups ofN-terminal valine in the Hb b-subunits react with the C-1 (aldehyde)carbons of monosaccharides to form aldimine adducts, whichrearrange to form very stable ketoamine products. Quantitation ofthis “glycated hemoglobin” is important clinically, especially fordiabetic individuals. Suggest at least three methods by which glycatedHb (also referred to as HbA1c) could be separated from normal Hband quantitatedEnzyme Activity and Physiological Function, The Vmax of the enzyme glycogen phosphorylase from skeletal muscle is much greater than the Vmax of the same enzyme from liver tissue.
