Chitosano

Descrizione:

Chitosano è un biopolimero derivato dalla chitina, che si trova negli esoscheletri di crostacei come gamberi e granchi. È caratterizzato dalla sua apparente polvere bianca a bianco sporco ed è solubile in soluzioni acide, rendendolo distinto dal suo precursore, la chitina, che è insolubile in acqua. Chitosano presenta diverse proprietà notevoli, tra cui biocompatibilità, biodegradabilità e non tossicità, che lo rendono adatto a varie applicazioni in medicina, agricoltura e industrie alimentari. La sua capacità di formare gel e film consente il suo utilizzo in sistemi di somministrazione di farmaci, medicazioni per ferite e come conservante alimentare. Inoltre, Chitosano possiede proprietà antimicrobiche, che possono inibire la crescita di alcuni batteri e funghi. Il grado di deacetilazione, che si riferisce alla proporzione di gruppi acetilici rimossi dalla struttura della chitina, influisce significativamente sulla sua solubilità e proprietà funzionali. In generale, Chitosano è un materiale versatile e rispettoso dell'ambiente con un'ampia gamma di potenziali applicazioni.

Chitosan

CAS: 9012-76-4

Chitosan is the deacetylated form of chitin. The polysaccharide is deacetylated in order to render it soluble, which is then possible at pH values of less than 7 (normally in dilute acid). This then allows the material to be used in a number of industrial applications as a binder and film former.Molecular weight range 350 - 3500 Da.
