Two-way communication: Cell communication often involves carbohydrate recognition. The simplest carbohydrate molecule already offers many ways to interact with a second one. Supersonic jet spectroscopy reveals the favorite communication channel based on equivalent hydrogen bonds, but on the corrugated potential energy landscape of glycolaldehyde dimer, the molecules may also get trapped in a metastable one-way communication mode, which is stabilized in hydroxyacetone.
