The experimental study aimed to select the spectrometric results of the solar flare that meet the mathematical conditions for integration, to measure the power of this integrated flux, and to test the integrated power, whether it is able to form a peptide bond between two molecules of selected amino acids on the Earth’s surface. Results show that the radiation power of the X17 solar flare scanned by the SOLSTICE and SIM spectrometers aboard the NASA SORCE spacecraft, when used for experimental irradiance of the same parameters, is sufficient to form methionine, alanine, glutamine and proline dipeptides in aqueous solution with pyrophosphate or carbonyl sulphide at laboratory temperature. The experiments, with their successful outcome, provide insight into the biological significance of the narrowband solar flare anchored in the broadband UV solar radiation.
