Tryptophan resonance structures
Did you know?
WebWhile 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. The oxygens share the negative charge with each other, stabilizing it, and reducing the charge on either atom. 2 comments.
