Coincidences - Organic chemistry

• One type of life on earth based on {$\text{CO}_2$} and {$\text{NH}_3$}. A local maximum based on the second law. The only kind possible in the universe? What is the probablility?
• Carbon (-4), nitrogen (-3), oxygen (-2) are like the foursome, threesome, twosome. And hydrogen (+1) is like the sevensome, slack. Life also uses phosphorus (-3) and sulphur (-2).
• The other end is (latently) carbon dioxide (with one bond removed and assigned to hydrogen). Are the two double bonds expressing the foursome?
• Ammonium {$− \textrm{NH}_3^+$} is a trianglular pyramid with the nitrogen atom at one vertex and the three hydrogen atoms at the other vertices. This shape makes the molecule polar and lets it bond with hydrogen to create {$− \textrm{NH}_4^+$}.
• Amino acids contain an amino {$− \textrm{NH}_3^+$} and carboxylate {$ − \text{CO}_{2}^{-}$} functional groups along with a side chain (R group). The amino and carboxylate can then link up so that there are long chains of amino acids. These particular links are the basis for all proteins and thus all of life. What is the geometry of the link? It seems very peculiar that all of life is based on this one link, that there is no alternate solution.
• Water, through hydrophilic and hydrophobic relations, is the medium that gives shape to all proteins, thus all living behavior. How does this medium act on the various amino acids?
• Could neutrinos be related to why DNA amino acids are left-handed rather than right-handed?
