Spectroscopic study of molecules propargylamine in the lab helped to find her in the cloud near the center of the milky Way. The researchers from Germany and Italy, wrote in the paper on arXiv.org.
Complex organic molecules astrogemini called units, which consist of six or more atoms and contain carbon. Of more than 200 molecules detected to date in interstellar space, only about 70 can be attributed to the complex. The study of these compounds should help to reveal the mechanism of formation of chemical complexity is to understand how from simple components have the structure needed to start biochemical processes on
the planet. Complex organic molecules which contain nitrogen, are a particular interest because it
they can serve as intermediate in the formation of biologically important types
molecules, such as nucleic acid bases and amino acids. How recent are formed outside of the Earth, there is no consensus.
Among the complex organic molecules that are widespread in the interstellar medium, until recently, was known six members of the class of Iminov. Hypothesis of their formation in space are based in most cases on the chemical route from a simple nitrile group via a tautomerisation or partial hydrogenation on the surfaces of particles of dust matter.
Bizzocchi Luca (Luca Bizzocchi) from the Institute for extraterrestrial physics max Planck and his colleagues at the National Institute of astrophysics of Italy decided to try to find in outer space another Imin — propargylamine, a structural isomer of the well-known astrophysicists molecules of Acrylonitrile. The formula of this unstable connection HCCCHNH. It is difficult to distinguish in terrestrial conditions, but at low density typical of the interstellar medium temperatures, it should feel good. Feature propargylamine molecule — its double carbon-nitrogen bond, which gives it a high reactivity. Molecule with such a bond involved in the reaction of Strecker, which is used in the laboratory for the synthesis of amino acids. Such reactions may occur in cold environments beyond Earth — as evidenced by the recent detection of the simplest amino acid glycine in the coma of comet 67P Churyumov-Gerasimenko.
Astrogemini received in the lab high-precision spectra of the two isomers propargylamine in the millimeter range and used these data to search for these isomers in interstellar space. Propargylamine found in the cloud G+0.693-0.027 in the Central molecular zone at a distance of about 500 parsecs from the galactic center.
Earlier we talked about how scientists have received “interstellar” glycine in the laboratory, as well as in the region of star formation found compounds that contain phosphorus is an important element for the formation of large biomolecules.
