Set of chemical reactions that resulted in the appearance of life.
Prebiotic chemistry is a set of chain reactions that produced what we call the first prebiotic molecules (sugar, amino acid and nitrogenous base). They were synthesised from liquid water and molecules containing carbon and then assembled into more complex compounds, macromolecules (protein and DNA), themselves the constituents of living matter
Four billion years ago, a complex chemical evolution is thought to have resulted in the formation of the first living things. This phenomenon involves a set of reactions. The first stage of this process is the production of what we call the prebiotic molecules (amino acid, sugar and nitrogenous base) from liquid water and certain carbon compounds. They were then assembled to form macromolecules (protein, DNA and RNA), the constituents of living matter. The chemical syntheses that led from inert matter to living matter are still not properly understood. To work out what these reactions were, chemists are attempting to recreate in the laboratory every stage of this evolution in the conditions on the primitive Earth.
