An Alkaline Chitin Solution and Some O-Alkylchitin Derivatives.

Production, properties, and some new applications of chitin and its derivatives.

Chitin is a polysaccharide composed from N-acetyl-D-glucosamine units. It is the second most abundant biopolymer on Earth and found mainly in invertebrates, insects, marine diatoms, algae, fungi, and yeasts. Recent investigations confirm the suitability of chitin and its derivatives in chemistry, biotechnology, medicine, veterinary, dentistry, agriculture, food processing, environmental protect...

Synthesis and characterization of some antifungal Oalkyl (O-aryl) trithiophosphato derivatives of 1,3,2- dioxaborinanes

Complexes of the type (OCH2C(CH3)2CH2OB)2S2P(S)OR (where R=Me,Et,Pri,Bui,Ph,CH2Ph) have beensynthesized by the reactions of 2-chloro-1,3,2-dioxaborinanes and potassium salt of O-alkyl (O-aryl)trithiophosphates in 2:1 molar ratio in refluxing benzene. The product are formed as white or light yellowcoloured monomeric solid, soluble in common organic solvents and exhibit high sensitivity towardsat...

Tumoricidal effect of O - carboxymethyl chitin , N , O - carboxymethyl chitosan and 2 - phtalimido chitin evaluation with human tumour cell line

Chitin is a nitrogen-containing polysaccharide, related chemically to cellulose. It is a principal constituent of the exoskeleton crustaceans. Due to their biocompatibility and less toxic nature, it has been developed as new physiologically bioactive materials since they possess various biological activities. Chemical extraction of chitin from shells, of the white shrimp Parapenaeus longirostri...

Applications of Chitin and Its Derivatives in Biological Medicine

Chitin and its derivatives-as a potential resource as well as multiple functional substrates-have generated attractive interest in various fields such as biomedical, pharmaceutical, food and environmental industries, since the first isolation of chitin in 1811. Moreover, chitosan and its chitooligosaccharides (COS) are degraded products of chitin through enzymatic and acidic hydrolysis processe...
