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.
