Untersuchungen zum Einfluss verschiedener Lösungsmittel und pH-Werte auf die spezifische Drehung. Identitätsprüfung am Beispiel des Arzneistoffs N-Acetyl-L-cysteins nach dem Europäischen Arzneibuch .
SUBSTANCES which exhibit optical activity in solution do so as a result of molecular dissymmetry, the most common cause of which is the presence of an asymmetric atom in the molecule. In the ...
Rheological measurement was employed to study the mutarotation of D-fructose in anhydrous state. By monitoring the evolution of shear viscosity with time, rate constants for mutarotation were ...
Lactose has two anomeric forms: α- and β-lactose. This study investigated the stability of solid lactose stored under high temperature and humidity conditions. Commercially available samples of ...
This article discusses the liquid chromatography instrumentation (columns, mobile phases, and detectors) that can be applied to determine different carbohydrates in human food and animal feeds.
ABSTRACT: With an adjusted model, we reconsider simple 1,2-dyotropic reactions with the introduction of a concept based on the intramolecular dynamics of a tetrahedron (van ’t Hoff modeling). In fact ...
