Why are ducks waterproof? It’s because they produce copious amounts of oils from their uropygial glands and spread it across their feathers. In this exercise, we’ll be investigating the molecular structure of one of these preen oils to determine how it keeps ducks dry.

- Silver ions are classified as a heavy metal, while sodium ions are not. Using this information, what do your results suggest about the stability of proteins in the presence of heavy metals?arrow_forwardWhat other factors can also affect the solubility of protein?arrow_forwardOxygen is transported around the body by the globular protein hemoglobin which contains four Fe2* ions. Hemoglobin is “oxygenated" when coordinated to dissolved oxygen in the blood. This can be simplistically represented by the following equation (where Hb represents one hemoglobin molecule): н (ад) + 402 (д) + нь(02)4 (аq) (1) Hemoglobin also readily binds with carbon monoxide (CO). Indeed, hemoglobin has a much higher affinity to CO than O2 resulting in significantly stronger hemoglobin binding to CO than to O2. This is a problem because hemoglobin molecules which are coordinated to carbon monoxide are unable to transport oxygen around the body as needed. No more than 2.5% of your body's hemoglobin can be bound to CO before health effects become noticeable. The consequence is that even very low partial pressures of CO in the air have physiological implications for humans. нь (ад) + 4Cо (д) + нь(со)4 (аq) (2) Compare and evaluate the relative magnitudes of the equilibrium constant for…arrow_forward
