WebbEine Hydrolyse ist die Spaltung einer chemischen Verbindung durch eine Reaktion mit Wasser. Dabei entstehen zwei Spaltstücke, also zwei neue Moleküle. Formal bindet hierbei ein Wasserstoffatom ( H) vom Wasser an das eine Spaltstück, der verbleibende Rest (- OH) an das andere Spaltstück. WebbHydrolysis is the cleavage of bonds in functional groups by reaction with water. This reaction occurs mainly in polymers that take up a lot of moisture and that have water-sensitive groups in the polymer backbone. Some synthetic polymers that degrade when exposed to moisture include polyesters, polyanhydrides, Webb9 nov. 2024 · Mechanism as antiurolithiasis remedy Parsley!
