Aldocyanoin microspheres: partial amino acid analysis of the microparticulates formed from simple reactants under various conditions.
The work of Kenyon and Nissenbaum on aldocyanoin microspheres was repeated and extended. It was determined that the microspheres contained amino acids and that specific amino acids could be incorporated into the microspheres by adding the requisite aldehyde or ketone precursor to the model mixture. Microsphere formation was found to be dependent on the availability of oxygen. Under anaerobic conditions of synthesis, no microspheres formed in the time allotted and the amino acid composition of the macromolecular material was simple. Microparticulate material synthesized by C. Folsome using a quenched spark technique was analyzed and found to contain amino acids that had a qualitative composition similar to both a Miller-Urey discharge and the Kenyon-Nissenbaum microspheres.
