Theories of a pre-RNA world suggest that glycolonitrile (HOCH$_2$CN) is a key species in the process of ribonucleotide assembly, which is considered as a molecular precursor of nucleic acids. In this Letter, we report the first detection of this pre-biotic molecule in the interstellar medium (ISM) by using ALMA data obtained at frequencies between 86.5$\,$GHz and 266.5$\,$GHz toward the Solar-type protostar IRAS16293-2422 B. A total of 15 unblended transitions of HOCH$_2$CN were identified. Our…

CAB: Towards the RNA-world in the interstellar medium -- detection of urea, and search of 2-amino-oxazole and simple sugars

In the past decade, Astrochemistry has witnessed an impressive increase in the number of detections of complex organic molecules. Some of these species are of prebiotic interest such as

The SKA as a Prebiotic Molecule Detector

The unmatched sensitivity of the Square Kilometre Array at centimeter wavelengths will be able to detect even more complex and heavier prebiotic molecules than existing instrumentation, as illustrated in this contribution.

Center for Astrobiology: Toward the RNA-World in the Interstellar Medium-Detection of Urea and Search of 2-Amino-oxazole and Simple Sugars.

Deep and high-sensitivity observations toward two of the most chemically rich sources in the galaxy are presented, revealing that urea is present in G + 0.693-0.027 with an abundance of ∼5 × 10-11, the first detection of this prebiotic species outside a star-forming region.

Gas-phase identification of (Z)-1,2-ethenediol, a key prebiotic intermediate in the formose reaction.

Prebiotic sugars are thought to be formed on primitive Earth by the formose reaction. However, their formation is not fully understood and it is plausible that key intermediates could have formed in

Glycolonitrile (HOCH2CN) Chemistry in Star-forming Regions

Glycolonitrile (HOCH2CN) is an attractive interstellar prebiotic molecule. Glycolonitrile is considered not only as a possible precursor for glycine but also as a key intermediate for adenine

Nitrogen heterocycles form peptide nucleic acid precursors in complex prebiotic mixtures

It is found that the majority of N-heterocycles, including the canonical nucleobases, gain short carbonyl side chains in the authors' complex mixtures via a Strecker-like synthesis or Michael addition, suggestive that PNAs could be prebiotically feasible on early Earth.

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.

Fate of the Gas-Phase Reaction Between Oxirane and the CN Radical in Interstellar Conditions

The escalating identification of new complex molecules in the interstellar medium claims for potential formation routes of such species. In this regard, the present work considers the reaction

The prebiotic molecular inventory of Serpens SMM1

Aims. Methyl isocyanate (CH3NCO) and glycolonitrile (HOCH2CN) are isomers and prebiotic molecules that are involved in the formation of peptide structures and the nucleobase adenine, respectively.
