Trope-a-Day: Mirror Chemistry

Mirror Chemistry: Played straight but in a much more complicated fashion.  After all, on Earth, life – for the most part – uses levoproteins and dextrosugars.  So there’s (trivially) four possible combinations right there, leaving aside more complex or dual arrangements, and that’s not even taking into account biochemistries that aren’t built around the same structural and energy molecules ours is, and/or that use the same compounds for completely different purposes…

Let’s just say that it’s really very important to pay attention to food labeling and the biochemical-compatibility plat attached to your restaurant menu.  Bartenders have fairly advanced degrees.  And if you throw a lot of polyspecific dinner parties, hire a specialist caterer.
