- Briefly indicate, with examples, the use of inorganic heterocycles in the synthesis of the corresponding polymers.arrow_forward1) Show how to use solid phase techniques to synthesize Ala-Val-Phe. You may use any amino acids (including protected amino acids) and any inorganic reagents that you wish in carrying out your synthesis. You don't need to show any mechanisms for this synthesis. You can maximize your chances of partial credit by showing key intermediates. (12 points)arrow_forward5) AZT is a drug that is used to treat HIV/AIDS. When cells take up AZT, they convert it to AZT- triphosphate. AZT-triphosphate prevents the virus from synthesizing new DNA from its RNA code. a.
