For each of the following statements, indicate whether they are true or false and, in the second case, correct them appropriately:
a) In biological systems, copper is often found in the form of blue proteins, so called because they absorb light from 450 to 500 nm
b) Aldehyde oxide reductase is a copper enzyme that oxidizes aldehydes to carboxylic acids
c) The only metal that carries oxygen transport in living beings is iron
d) Superoxide dismutase catalyzes the decomposition of the anion superoxide in water and hydrogen peroxide
e) Holochromodulin is activated when insulin levels decrease, binding to its receptors.
f) Ferredoxins are metalloproteins present in the liver of all animals, whose purpose is to store iron
Ancient peoples used salicin to reduce fevers. Write an equation for the acid-catalyzed hydrolysis of the glycosidic bond of salicin. Compare the aromatic product with the structure of acetylsalicylic acid (aspirin). Use this information to develop a hypothesis explaining why ancient peoples used salicin to reduce fevers.
In solution, glucose is mostly found in the cyclic hemiacetal state, which lacks an aldehyde group. How are mild oxidising agents able to oxidise glucose?
