HMG-CoA reductase, a critical enzyme in cholesterol synthesis is the target or statin inhibitors. You are characterizing a possible new inhibitor and want to determine its mode of binding to HMG-CoA reductase. Equilibrium dialysis measurements at 25 C, 30°C, and 37 C yielded dissociation constants (K.) of 2.5 x 10" М, 1.5 x 10", and 1.0 x 103 M, respectively, for the HMG-CoA reductase-inhibitor complex. a. Is the binding becoming better or worse with increasing temperature? Explain. b. Using Excel...

Problem 1. Metabolism
Carotenoid-derived compounds such as ionones and pseudoionone
constitute essential aromas in tea, roses, tomato, wine and
tobacco. Pseudoionone is a valuable acyclic intermediate for the
chemical synthesis of ionones. Thus, there has been several
attempts to produce this compound in a heterologous host as shown
below.
In the figure above the enzymes (here shown as gene names) are
given in Italics and chemical compounds in
non-italics.
The figure shows that pseudoionones are produced from the
general terpenoid...
