8. Dopamine is a neurotransmitter (chemical messenger) between nerve cells. Deficiency of dopamine results in Parkinson's disease. Administration of dopamine does not stop the symptoms of this disease because dopamine in the blood cannot cross the blood-brain barrier. The drug Dopa, however, does give relief from Parkinson's symptoms. It can pass through the blood brain barrier and is converted by enzymes inside brain cells to dopamine: но- poOH -CH2CHNH2 HO ÇOOH CO2 HO но- -CH2CH2NH2 Dopa Dopamine This reaction is an example of O acid - base reaction G addition 6 substitution elimination

Directions: Using all resources available to you, investigate the chemical procedure known as the Ostwald Process and answer the following questions fully: a) What is the core chemical equilibrium (or equilibria) associated with this process? Write the balanced chemical equation(s). b) Write the expression for the equilibrium constant of this reaction. c) Draw and label a general diagram of the process. See the final slide of Chapter 13 illustrating the Haber-Bosch Process as an example. Provide details such as temperature, pressure, presence and identity of a catalyst, etc. d) What elements of this process utilize Le Chatelier's Principle to improve production of the desired product? e) Are there elements that do not utilize Le Chatelier's Principle but still aid in creating the product?
