Question

Questions relating to isoprenoid metabolism What is the net reaction for the synthesis of Dimethylallyl Pyrophosphate from Acetyl-CoA? Please write a balanced chemical equation and remember to include any carbons lost as carbon dioxide as well as any co- factors that change their phosphorylation/oxidation states, e.g. NADPH -> NADP+ and ATP ? ADP + Pi. (A) (B) Name two biological compounds synthesized from Isepenteny Pyrophosphate and/or Dimethylallyl Pyrophosphate Name a compound derived from HMG-CoA that is not an ?soprenoid/ terpenoid (C)

Explanation / Answer

1. Acetyl CoA + ATP------- Dimethylallyl pyrophosphate + CO2 + Pi

2. Dimethylallyl pyrophosphate ------ Squalence
Dimethylallyl pyrophosphate ------ Beta carotene

3. HMG-CoA to Acetyl-CoA
HMG-CoA to Beta hydroxybutyrate
