WebMay 27, 2024 · We found that crystalline chitin exhibited a characteristic Raman peak at 2995 cm −1, which did not appear in the reaction product, N, N ′-diacetylchitobiose. We used this Raman peak as a marker of crystalline chitin degradation to monitor the hydrolytic activity of chitinase. WebFeb 1, 2006 · Abstract. Roentgenographic studies are performed to investigate the structural changes in chitin under pressure and shear during its solid-state processing using a twin-screw extruder and Bridgman ... WebFinally, this work found that fungal cell wall compounds, likely chitin, were not degraded, and were still detectable even after high UV irradiation doses. The implications for the preservation and detection of biosignatures in extraterrestrial environments are discussed. ...
