Yes, Walter, there is a polymorph of sucrose! At 4.80 GPa, (+)‐sucrose, common table sugar, transforms into a new polymorph. In its structure the network of intermolecular hydrogen bonds is reformulated, with new types of H bonds being formed, and the molecular conformation changes. This structural variability is characteristic of all carbohydrates, hinders their crystallization, and is vital for organisms for which sugars are important building blocks.
Es gibt ein Polymorph von Sucrose! Bei 4.8 GPa wird der übliche Haushaltszucker (+)‐Sucrose in ein Polymorph überführt, dessen Struktur ein neu geordnetes intermolekulares Wasserstoffbrückennetzwerk, neue Arten von H‐Brücken sowie eine geänderte Molekülkonformation aufweist. Diese Variabilität ist charakteristisch für Kohlenhydrate, behindert ihre Kristallisation und ist entscheidend für Organismen, für die Zucker wichtige Bausteine sind.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
