Sweet truth: The search for sugars in interstellar space is hampered by a lack of spectroscopic information. D-Ribose is now the first C5 sugar observed in the gas phase using microwave spectroscopy. The rotational spectrum revealed six conformations of free ribose, adopting preferentially β-pyranose rings and higher-energy α-pyranose forms. No evidence of α-/β-furanoses or linear forms was found, unlike biological systems, where β-furanoses are found in RNA.
