a lot of the biochemistry we look at in metabolism is more like electrochemistry than organic chemistry, or "o chem" per se. O chem focuses more on structure and the mechanisms by which reactions occur, classifications of molecules, etc. This branch of chemistry is more involved in understanding how various enzymes, hormones, receptors and transporters operate to facilitate our biochemistry. But the reactions themselves and what drives them in our bodies are not a whole lot different than the metallurgical electrochemistry, we're basically talking biological and physical electrochemistry -- what I'll call biophysical electrochem for short.
