In this book a comparative study on the extraction of chitin and chitosan from Giant tiger prawn (Penaeus monodon) shell in biological applications, Antiplatelet and Anti-glycation activity. The naturally abundant polysaccharide, chitin was extracted from giant tiger prawn shell by demineralization and deprotenization process. Then the small amount of extracted chitin was converted to chitosan by deacetylation process. The presence of chitin and the quality of chitosan was verified by chemical test and solubility test. The concentration of chitosan in acetic acid is noted. It was observed...
