Someone could also replace the carbon with silicon.

Silicon/Bismuth biochemistry is way more limited than Carbon/Hydrogen Oxide biochemistry in terms of temperature range and stable compounds. Silicon/Hydrogen Sulfide biochemistry does not work at all because hydrogen sulfide does not have the point of least volume.

biochemistries listed here are denoted as bonding atom/solvent pairs.
