Laboratory simulation of ultraviolet irradiation from the Sun on amino acids. III. irradiation of glycine-tyrosine

The effects of near ultraviolet (UV) radiation oil water solutions of tyrosine and glycine-tyrosine are investigated using a broadband xenon lamp in the region 200-800 nm. These experiments form a contribution in the laboratory simulation of the solar irradiation oil the building blocks of life with regard to the origin of life. Results are presented showing the photodecomposition of tyrosine and glycine-tyrosine, at different concentrations, against UV closes. The analysis of the irradiated Solutions is carried Out by spectroscopic and analytical techniques. The findings of our laboratory Simulations are used to constrain the early stages of the life emerging process.
