I think that you are sorta close, but you mean "oxidized adrenaline". When the oxidation of Adrenaline(C9H13NO3) occurs, it forms adrenochrome(C9H9NO3). When epinephrine reacts with oxygen(O2), the oxygen molecule splits and they each steal two hydrogen atoms. This reaction produces two molecules of oxidized hydrogen and adrenochrome. C9H13NO3 +O2 ----> 2 H2O + C9H9NO3 I used oxygen because it was appropriate and easy, but there are other substances that could cause the oxidation reaction to occur.
