While it isn't used to sweeten foods, it is important because scientists think it plays a key role in the chemical reaction that forms ribonucleic acid (RNA), a crucial biomolecule present in all living cells.

It's still unclear exactly how glycoaldehyde is produced in space, but observations suggest it forms on ice-covered dust grains in the dense, cold parts of interstellar molecular clouds, Jørgensen said.
