Homopoly condensation

Simplicity of structure and ease of formation makes it reasonable to infer that polyP and PHB were components of early cells, possibly preceding RNA. PolyPs are prebiotic molecules, formed by condensation of phosphates in volcanic condensates and thermal vents at the bottom of the ocean.2,34,146 The synthesis of PHB is more demanding but requires only acetate and a reducing agent (see Figure 2B), both available in the primordial milieu. The conservation of these rudimentary homopoly-...
