The biological molecules delivered to Earth on the board of meteorites and comets were called one of the possible causes of the origin of life. Therefore, our understanding of the routes of formation of biomolecules in space should shed the light on the possibility of the existence of habitable extrasolar planets. The large abundance of organic molecules is found in the space regions with the lowest temperature. Different routes of the organics formation in these areas were suggested. In this…

Glycine Peptide Chain Formation in the Gas Phase via Unimolecular Reactions.

Peptide chain formation from amino acids such as glycine is a key step in the emergence of life. Unlike their synthesis by living systems, how peptide chains grow under abiotic conditions is an open

Unraveling sulfur chemistry in interstellar carbon oxide ices

Formyl radical (HCO•) and hydroxycarbonyl radical (HOCO•) are versatile building blocks in the formation of biorelevant complex organic molecules (COMs) in interstellar medium. Understanding the

Intrinsic disorder, extraterrestrial peptides, and prebiotic life on the earth.

Bioinformatics analyses strongly predict such homo-polymeric peptides to be intrinsically disordered underscoring the potential involvement of IDPs in the origin of life which, even in its simplest form, could emerge spontaneously by autocatalysis of the primordial IDP in self-organizing systems that evolved over time following natural selection.

A pathway to peptides in space through the condensation of atomic carbon

Organic molecules are widely present in the dense interstellar medium, and many have been synthesized in the laboratory on Earth under the conditions typical for an interstellar environment. Until

Formation pathways of proteins in space

Until now, experiments demonstrated the possible formation of relatively small prebiotic molecules under typical space conditions. We demonstrated experimentally that condensation of atomic carbon

Discovery in space of ethanolamine, the simplest phospholipid head group

Significance The detection of ethanolamine (NH2CH2CH2OH) in a molecular cloud in the interstellar medium confirms that a precursor of phospholipids is efficiently formed by interstellar chemistry.

Chemistry and physics of dopants embedded in helium droplets.

Development of experimental techniques and methods and recent results they enabled to grow complexes and clusters at conditions that are perfect to simulate cold and dense regions of the interstellar medium are summarized.

An Experimental and Theoretical Investigation into the Formation of Ketene (H2CCO) and Ethynol (HCCOH) in Interstellar Analog Ices

The formation of isomers of C2H2O—ketene (H2CCO), ethynol (HCCOH), and oxirene (c-CHCHO)—was investigated in interstellar ice analogs composed of carbon monoxide and water. Using tunable

A cryogenic ice setup to simulate carbon atom reactions in interstellar ices.

The design, implementation, and performance of a customized carbon atom beam source for the purpose of investigating solid-state reaction routes in interstellar ices in molecular clouds are discussed, which includes the flux of the carbon atoms hitting the ice sample, their temperature, and the potential impact of temperature on ice reactions.

Sensitivity of gas-grain chemical models to surface reaction barriers

Context. The feasibility of contemporary gas-grain astrochemical models depends on the availability of accurate kinetics data, in particular, for surface processes. Aims. We study the sensitivity of

Condensation of Atomic Carbon: Possible Routes toward Glycine

Many organic molecules including amino acids and nucleobases are expected to be formed in astrophysical environments. In this article, we used both experimental and computational approaches to test
