WebCreatine phosphate may be equally important as a stabilizing energy source in the brain. It has been suggested that high-energy phosphates help to maintain membrane potentials, participate in neurotransmitter release, contribute to calcium homeostasis, and play roles in neuronal migration, survival, and apoptosis ( Wyss and Kaddurah-Daouk, 2000 ). WebThe two oxygens are both partially negative, this is what the resonance structures tell you! While both resonance structures are chemically identical, the negative charge is on a different oxygen in each. This is important because neither resonance structure actually exists, instead there is a hybrid.
