replaced MathJax with Markdown table (more accessible) https://rpg.meta.stackexchange.com/questions/11370/are-markdown-tables-superior-to-mathjax-arrays-for-accessibility

I've answered questions related to this a couple of times and link those questions here (What are some biochemical alternatives to carbon) and here (Life on a Molten World).

My reference is the always valuable Atomic Rockets website: Building Blocks. This resource provides the references it used to develop its list.

$$\begin{array}{|c|c|c|c|} \hline \text{Min Temp} & \text{Max Temp} & \text{Macromolecule} & \text{in Solvent} \\ \hline \text{400° C} & \text{500°?

This table does not identify the information carrying molecule that might go with the solvent and building block molecule.

Atomic Rockets lists these other solvent & macromolecule possibilities (but doesn't list suggested temperature ranges):

  • Ammonia - (shown) could replace water as a solvent. At high pressures, ammonia remains a liquid over a larger temperature range than water.
  • Boron - boron nitrides could replace carbon chains as a macromolecule. Boron Nitrides may work better with Ammonia solvent than carbon macromolecules would.
  • Nitrogen - combined with other elements (Boron, Sulfur, or Phosphorus) could replace carbon chains as a macromolecule.
  • Phosphorus - combined with other elements (Carbon, Nitrogen, or Silicon) could replace carbon chains as a macromolecule.

There are even more extreme possibilities.
