Sugars are essential #biomolecules, serving as metabolic fuels, nucleic acid backbone components and structural or energy-storage polymers.
A central question in origin-of-life research is how monosaccharides formed on the primitive Earth, as laboratory experiments under #prebiotic conditions yield insufficient concentrations.
The detection of #ribose, #glucose and other monosaccharides in #asteroids and #meteorites suggests an exogenous origin, possibly in the interstellar medium (ISM) before meteoritic parent-body formation.
However, no #sugar has been observed in the ISM so far.
Now astronomers report the discovery of #erythrulose, a chiral four-carbon ketose, in the ISM.
Erythrulose appears to be at least eight times more abundant than analogous three-carbon sugars, which remain undetected in our ultrasensitive observations.
Quantum chemical and astrochemical models indicate that erythrulose forms efficiently on interstellar dust grains from simpler two-carbon aldehydes and alcohols.
As ketoses readily isomerize into aldoses in aqueous conditions, interstellar erythrulose could have contributed to the sugar inventory available for early metabolic and replication processes.

The Chicxulub impact was a quick and catastrophic event with lasting consequences. Not talking about the thing with the dinosaurs - it drove significant hydrothermal activity for 8 million years across the entire region.
