Back titration: The major component of eggshells is calcium carbonate (CaCO3)(CaCO3) . To determine its calcium content, a back titration was done as described. 0.7520 g of dry, crushed eggshell was placed into an Erlenmeyer flask and dissolved with 25.00 mL of 1.026 M HCl according to the following reaction. CaCO3(s)+2HCl(aq)→CaCl2(aq)+H2O(l)+CO2(g)CaCO3(s)+2HCl(aq)→CaCl2(aq)+H2O(l)+CO2(g) To assist with the reaction between the HCl and CaCO3CaCO3 , the solution was heated to a boil, and then left to cool. Once no more CO2(g)CO2(g) was being produced (the bubbling had stopped), approximately 25 mL of deionized water was added to the flask, and its contents were quantitatively transferred to a 100.00 mL volumetric flask. The volumetric flask was filled to the mark with deionized water and mixed. A 25.00 mL aliquot of the diluted CaCO3CaCO3 sample was pipetted into a separate Erlenmeyer flask and titrated with 22.96 mL of standardized 0.1080 M NaOH to the phenolphthalein end point.…
N-acetylphenylalaninamide 2. (a) is a substrate of a-chymotrypsin. Draw the structural formula of this molecule, indicate which bond is cleaved in the hydrolytic reaction, and explain from its structure why it is a specific substrate of a-chymotrypsin. What influence does the acetyl group have on the reaction? (b) The table on the right lists initial velocity data for hydrolysis of N-acetylphenylalaninamide catal- yzed by a-chymotrypsin. From the data calculate the value of KM by a graphical method using a rectangular hyperbolic function to relate velocity to substrate con- centration and compare the results to the value obtained by a linear least-squares fit of the data in the form of a double-reciprocal plot.

One biochemical strategy of many living organisms is the stepwise oxidation of organic compounds to CO₂ and H₂O and the conservation of a major part of the energy thus produced in the form of ATP. It is important to be able to recognize oxidation- reduction processes in metabolism. Reduction of an organic molecule results from the hydrogenation of a double bond (Eqn 1) or of a single bond with accompanying cleavage (Eqn 2). Conversely, oxidation results from dehydrogenation. In biochemical redox reactions, the coenzymes NAD and FAD dehydrogenate/hydrogenate organic molecules in the presence of the proper enzymes.
