In fatty acid metabolism, one of the metabolic order defects is MCAD (medium-chain acyl- CoA dehydrogenase) deficiency, an autosomal recessive disorder, where vomiting and lethargy are triggered when an affected individual does not eat for an extended period of time. A different, rarer, disorder is MCAT (medium-chain ketoacyl-CoA thiolase) deficiency, which presents in similarly to MCAD, though has rarely been reported. Why do you think these two disorders are rare, and what would the difference in metabolites be (i.e. which...

40.Fatty acid synthase is an enzyme in the lipid metabolism pathway, that: A. occurs in the mitochondrion in animal cells, 2 nor Section A B. utilises NADH as an electron donor C) requires NADPH as a substrate. D. requires acetic acid as a substrate. E. consists of a single multifunctional protein in plants and bacteria. 41.One round of beta oxidation produces 1 molecule of acetyl-CoA from a saturated Acyl-CoA molecule. Which reducing equivalents are made in this process in which...

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 (Ks) of 2.5 x 10* M, 1.5 x 10*, and 1.0 x 10* M, respectively, for the HMG- CoA reductase-inhibitor complex a. Is the binding becoming better or worse with increasing temperature? Explain. b. Using Excel or...
