A Computational Study of the Prebiotic Photochemical Synthesis of L-Ascorbic Acid, and D-sugars: Glucose, Amylose and Cellulose
Author:
Abstract: Ab initio applied computing is used to determine a viable and plausible mechanism for the formation of L-ascorbic acid, and D-sugars: glucose, amylose and cellulose. from planetary or interstellar gases that contain the necessary essential elements. Each compound is formed from carbon monoxide, hydrogen and water. The surface catalyst for the formation of the monosaccharides and polysaccharides is taken to be the photochemically activated surface catalyst of the metalloporphyrin, ferrous porphin, itself formed from diacetylene cyanide. The bonding of the carbon monoxide to form a hexadentate Fe. porphin, may produce each of the monosaccahrides, whereas the formation of a glucose furanoside susceptiple to polymerization enables the formation of both α(1-4) amylose and β(1-4) cellulose. The intermediates for the formation of these residues are characterized by their reaction enthalpies and activation energies. The reactions have been shown to be feasible from the overall enthalpy changes in the ZKE approximation at the HF and MP2 /6-31G* level, and with acceptable activation.
