Reactive oxygen species (ROS) are unstable oxygen-containing molecules that can cause damage to enzymes and membranes. Cells can defend against damage by converting these ROS to Harmless species.
Complete the following reactions by replacing the question mark with the appropriate formula. Choose the correct enzyme or enzyme class.
What is the pH of the final solution? Answer IS 7.58 Q 3.) What additional volume of 10.0 M HCl would be needed to exhaust the remaining capacity of the buffer after the reaction described in Part B?
When ammonia is added to nickel ions in aqueous solution, the water molecules bound to the Ni2+ are replaced by ammonia molecules.
Show how to make N-methylpropionamide using propionic acid and methylamine and other necessary reagents. The methylamine and propionic acid do not both have to be used in the first step.
