please let it be on the computer is that later I don't understand

6. Interaction between two (or more) molecules in solution can be mediated by specific hydrogen bonding interactions. Phorbol esters can be tumor promoters by binding to certain amino acids that are part of the enzyme protein kinase C (PKC, for protein kinase C). Trace the hydrogen bonds expected to form in the complex between the tumor-promoting phorbol and the glycine part of PKC, -NHCH;C(O)- H R R 0 Forbol 8. You are instructed to prepare 100 mL of a phosphate buffer, pH = 7.2, by mixing 50 mL of solution A (NaHPO, 0.02 M) and 50 mL of solution B (NaHPO, 0.02M). See Table 2.4 to explain why this procedure prepares that buffer well at the desired pH and concentration
