Chitin a polymer

WebFeb 17, 2024 · Chitin exists as a linear polymer of N-acetyl-D-glucosamine units linked together by β-1,4-glucosidic linkages. This structure results in a three-dimensional α-helix configuration. The stability of the α-helix chitin structure is brought about by the hydrogen bonding of the N-acetyl side chains. WebMay 29, 2024 · Γ-chitin is a mixed composition of forms α and β [7,9]. Α-chitin can be transformed into β-chitin, but not the reverse . The three allomorphs can be observed by X-ray diffraction and Nuclear Magnetic Resonance (NMR) . The degradability of the polymer occurs through the action of the enzyme chitinase, present in nature .
