Why are carbs, amino acids, and nucleic acids not molecules found in an inorganic solution?

Question

Why has all life has come to depend on their availability? Doesn’t that dependence make life fragile? How does that dependence make all of life interdependent on one another, and how does that dependence affect human beings?

Answer 1

Amino acids and nucleic acids are hydrocarbons. Organic chemistry is everything made up of hydrocarbons. So they cannot be found in inorganic solutions. When considering inorganic chemistry and life, it is useful to recall that many species in nature are not compounds per se but are ions. Sodium, chloride, and phosphate ions are essential for life, as are some inorganic molecules such as carbonic acid, nitrogen, carbon dioxide, water and oxygen. Aside from these simple ions and molecules, virtually all species covered by bioinorganic chemistry contain carbon and can be considered organic or organometallic.

The only inorgani compunds contain carbon are, carbon monoxide, carbon dioxide, carbonates, cyanides, cyanates, carbides, and thyocyanates.
