The interstellar medium is characterized by a rich and diverse chemistry. Many of its
complex organic molecules are proposed to form through radical chemistry in icy grain …

Proteins of all living organisms including plants, animals, and humans are made up of amino
acid monomers that show identical stereochemical l-configuration. Hypotheses for the origin …

Context. Complex organic molecules (COMs) are ubiquitously detected in the gas phase
and thought to be mostly formed on icy grains. Nevertheless, there have not been any …

Within the cold regions of space, ices that are enriched with carbon monoxide (CO)
molecules are exposed to ionizing radiation, which triggers new reactions and desorption …

Astrophysical ices are being exposed to ionizing radiation in space environments, which
trigger new reactions and desorption processes. In the lab, such processing by radiation has …

Proline is a unique amino-acid, with a secondary amine fixed within a pyrrolidine ring
providing specific structural properties to proline-rich biopolymers. Gas-phase proline …

In this work, the chemical evolution of pure acetonitrile ice at 13 K irradiated with broad-band
soft X-rays (from 6 eV to 2 keV) is determined by using a computational methodology …

Chemical reactions and desorption processes are being triggered by incoming ionizing
radiation over astrophysical ices in cold space environments. The quantification of these …

The polymerization of amino acids leading to the formation of peptides and proteins is a
significant problem for the origin of life. This problem stems from the instability of amino …

Glycine is the simplest proteinaceous amino acid and is present in all life-forms on Earth. In
aqueous solutions, it appears mainly as zwitterion glycine (+ NH3CH2COO−); however, in …
