"Silicon based life" is a perennial sci-fi trope - I guess because silicon and carbon share similar-ish valency properties. Has anyone actually tried to flesh out what a silicon chemistry complex enough to support protein analogues would look like? Or more broadly, has anyone proposed schemata for complex, self-replicating chemistries that differ substantially from those we know?
Looking for a chart or table that broadly summarizes/compares the relative bond energies of the most common intramolecular bonds found in organic molecules (think single and double bonds among C, H, O, N, and maybe S too). [more inside]
What's this molecule? An antibiotic of some kind, I think? I've tried Google'ing based on its IUPAC name, no luck.

Organic Chemistryfilter: In H NMR spectroscopy, why is it that as a carbon is more substituted, it is also more shielded? Better explanation inside. [more inside]
