Glycine (Gly), NH2CH2COOH, is the simplest amino acid. Although it has not been directly
detected in the interstellar gas-phase medium, it has been identified in comets and …

The celebrated Miller experiments reported on the spontaneous formation of amino acids
from a mixture of simple molecules reacting under an electric discharge, giving birth to the …

Increasing experimental and theoretical evidence points to formamide as a possible hub in
the complex network of prebiotic chemical reactions leading from simple precursors like H2 …

Methylamine CH3NH2 is considered to be an important precursor of interstellar amino acid
because hydrogen abstraction might lead to the aminomethyl radical• CH2NH2 that can …

Glycine and methylamine are meteoritic water-soluble organic compounds that provide
insights into the processes that occurred before, during, and after the formation of the Solar …

Several organic chemical compounds (the so-called interstellar complex organic molecules,
iCOMs) have been identified in the interstellar medium (ISM). Examples of iCOMs are …

We studied the effects produced by the interaction of heavy ion cosmic rays with interstellar
and cometary organic molecules in the solid phase. Formic acid (HCOOH) ice at 15 K was …

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 …

We investigate the effects produced mainly by broadband soft X-rays up to 2 keV (plus fast
(∼ keV) photoelectrons and low-energy (∼ eV) induced secondary electrons) in the ice …

In this study, quantum chemical calculations were used to explore the synthesis of three
chiral α-amino acids, specifically alanine, serine, and isovaline, from reactants found in …
