About the Book

Neste livro é feito um estudo comparativo sobre a extração de quitina e quitosano da casca do camarão-tigre-gigante (Penaeus monodon) em aplicações biológicas, atividade antiplaquetária e antiglicação. O polissacárido naturalmente abundante, a quitina, foi extraído da casca do camarão-tigre gigante através do processo de desmineralização e desproteinização. Em seguida, a pequena quantidade de quitina extraída foi convertida em quitosano por processo de desacetilação. A presença de quitina e a qualidade do quitosano foram verificadas por testes químicos e testes de solubilidade. A concentração de quitosano em ácido acético é registada. Observou-se que o quitosano extraído era mais facilmente solúvel em solução de ácido acético a 1%, o que mostrava que o quitosano estava na forma pura. A análise FT-IR da quitina mostrou as bandas correspondentes ao estiramento das ligações O-H, N-H e CO, o que confirmou a quitina. A análise FT-IR do quitosano mostrou bandas correspondentes ao grupo amino, que se verificou ser o grupo principal que indica o quitosano. Com base nos resultados do ensaio em microplacas de Giemsa e do ensaio espetrométrico, concluiu-se que o quitosano mostrou maior eficácia na atividade antiplaquetária do que a amostra de quitina.
