Products obtained from this structure
The biochemical degradation of isoleucine goes through the intermediate tiglyl‑CoA, shown as the starting material in the scheme. This route is similar to the β‑oxidation of fatty acids. Complete the structure of the intermediate and product of this reaction. The carbon skeleton and acetyl CoA thioester have been predrawn for you. Do not delete any atoms or bonds.
Water production from fatty acid oxidation is a survival mechanism in animals where water is scarce. Cells oxidize palmitoyl-CoA to produce water. If an animal has 5.000 kg of palmitoyl-CoA available for fatty acid oxidation, how many kilograms of water could the animal produce from that palmitoyl-CoA? The chemical formula for palmitoyl-CoA is C37H66N7O17P3S.
