To determine the number of different B vitamins that participate in the reactions involved in the metabolism of carbohydrate. Concept introduction: Carbohydrates are the biomolecules composed of carbon, oxygen and hydrogen atoms. Carbohydrate molecules are joined together by glycosidic linkage. Carbohydrates are an important source of energy and therefore, they are important parts of human nutrients. In glycolysis, glucose is converted into pyruvate; in glycogenesis, glucose 6 − phosphate is converted into glycogen; in glycogenolysis, glycogen is converted to glucose 6 − phosphate ; in gluconeogenesis, a non-carbohydrate substance is converted into glucose; pyruvate is converted to acetyl CoA under oxygen-rich conditions and to lactate under oxygen-poor conditions in the human body. Vitamins are defined as the micronutrients that are needed in a small amount for the proper functioning of the metabolic activities in the organisms. Coenzymes are non-protein organic compounds that are used along with the enzymes and help to carry forward the reaction. Coenzymes cannot perform on their own alone.

a. The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 " is best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: HO + :Ö: Bicarbonate is crucial for the control of body pH (for example, blood pH 7.4). A more self-indulgent use is in baking soda, where it serves as a source of CO2 CO2 gas, which gives bread and pastry their fluffy constituency. (i) Draw at least one additional resonance form. = (ii) Using curved "electron-pushing" arrows, show how these Lewis structures may be interconverted by movement of electron pairs. (iii) Determine which form or forms will be the major contributor(s) to the real structure of bicarbonate, explaining your answer on the basis of the criteria in Section 1-5.
