This polysaccharide is a primary component of cell walls in fungi , the exoskeletons of arthropods , such as crustaceans and insects , the radulae of molluscs , cephalopod beaks , and the scales of fish and skin of lissamphibians. It is functionally comparable to the protein keratin. Chitin has proved useful for several medicinal, industrial and biotechnological purposes.

Merzendorfer , L. It is mainly produced by fungi, arthropods and nematodes. In insects, it functions as scaffold material, supporting the cuticles of the epidermis and trachea as well as the peritrophic matrices lining the gut epithelium. Insect growth and morphogenesis are strictly dependent on the capability to remodel chitin-containing structures.

Corresponding Author. This review characterizes the most common natural polysaccharides and the presence of huge structural tendencies for the production of biologically active compounds, which have innovative characteristics and functions of different applications, especially in the field of biomedicine. Their applications are also demonstrated, such as: biomedicine antioxidant, anti-bacterial, anti-fungal anti-viral, hepatoprotective, cardiovascular, anti-hypercholesterolemia, anti-parasitic, anti-diabetic, detoxification, anti-tumor and immunomodulating , agriculture, food industry, textile industry, and paper making. Interestingly, the relationship between biological activity and chemical structure is elucidated for glucan, chitin, chitosan molecules with various degree of acetylation DA and Mw. In conclusion, many vital industrial and medical applications are offered, for chitin, chitosan and glucan, and they are known as vital and a novel biological compound, which have occupation priority of their compatibility low immunogenicity and nontoxic and biodegradation with non-toxic.

Chitin, Chitosan and Glucan, Properties and Applications

Fungi are unicellular or multicellular thick-cell-walled heterotroph decomposers that eat decaying matter and make tangles of filaments. Fungi are eukaryotes and have a complex cellular organization. As eukaryotes, fungal cells contain a membrane-bound nucleus where the DNA is wrapped around histone proteins.
