Acid anhydride
- We draw a carbon, double-bonded to an oxygen and single bonded to another oxygen atom.
- To the single-bonded oxygen atom, we add another carbon double-bonded to an oxygen.
- We add R groups on either side so that each carbon has four bonds.
Acid anhydrides are quite reactive. Notable acid anhydrides include ATP, the energy currency of the cell ands 1,3 bisphosphoglycerate, an intermediate formed in glycolysis, which is commonly known for its role in energy release but also has significant roles in numerous other biochemical processes.
