- Draw the structure of fulvic acid chelated with Pb²+ at pH 8.0.please explain why this happends, im having trouble in this section. Part A Chymotrypsin, an enzyme that hydrolyzes peptide bonds in proteins, functions in the small intestine at an optimum pH of 7.7 to 8.0. How is the rate of the chymotrypsin-catalyzed reaction affected by each of the following conditions?The BOD rate constant was found to be 0.151 day^-1 (base e) at 28.5 Celsius. What is the rate constant day^-1 (base e) at 6.0 Celsius?
- When some sugars dissolve in water they spontaneously undergo changes in optical rotation called mutarrotation. The Mutarrotation of D-glucopyranose is catalyzed by acid and bases. 2-Hydroxypyridine is a more effective catalyst than phenol and pyridine for this reaction because: a.Both oxygen and N in 2-hydroxypyridine act as bases increasing the rapid interconversion of sugar b. The OH of 2-hydroxypyridine serves as the base while the current N as the acid. c. 2-hydroxypyridine acts both as a base to remove the proton from the hydroxyl group in the hemiacetal and as an acid to provide a proton to the oxygen in the hemiacetal. d.Phenol and pyridine are very expensive.What is the product of the reaction sequence shown in Image 34?The rate constant for the uncatalyzed reaction of two molecules of glycine ethyl ester to form glycylglycine ethyl ester is 0.6 M- 1s - 1. In the presence of Co2 +, the rate constant is 1.5 * 106 M- 1s - 1. What rate enhancement does the catalyst provide?
