DOI : Background: Chitosan CS is a biomaterial derived from chitin, known for its excellent biological properties. One of the most interesting features of CS is its potential for chemical derivatization, which makes it a versatile material and allows to expand its applications.

Chitin and chitosan: Chemistry, properties and applications

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 can be extracted from the exoskeletons of crustaceans, insects and mollusks and the cell wall of microorganisms. It can be converted into chitosan by deacetylation process. Chitosan shows more versatility than chitin due to its solubility and reactive free amino group -NH 2. This article helps to understand the importance and characteristics of chitin and chitosan by their various aspects such as properties and medical and industrial applications.

Chitin and chitosan: Chemistry, properties and applications

The main objective of the present work is to develop and characterize a new generation of adsorptive gelled porous bead supports made from nanoparticles of chitosan, bentonite and alginate. There were subsequently used in the purification of water synthetically polluted with cupric ions. Adsorption kinetics is better described by the expression of the second-order model whereas the adsorption isotherm is satisfactorily described by the Freundlich model. Chitosan is a polysaccharide that deserves special attention due to its net cationic character and to the presence of multiple reactive functional groups OH and NH 2 on its chains. The use of chitosan in acid conditions to remove heavy metals is limited due to its tendency to dissolve in acid effluents. To overcome this problem, chitosan was stabilized by crosslinking in acid conditions 1 , 2 , 3.

 Что значит - пробовал. Стратмор развернул монитор так, чтобы Сьюзан было. Экран отливал странным темно-бордовым цветом, и в самом его низу диалоговое окно отображало многочисленные попытки выключить ТРАНСТЕКСТ. После каждой из них следовал один и тот же ответ: ИЗВИНИТЕ.

Пуля ударилась о мрамор совсем рядом, и в следующее мгновение он уже летел вниз по гранитным ступеням к узкому проходу, выходя из которого священнослужители поднимались на алтарь как бы по милости Божьей.

Applications of Chitin and Chitosan in Industry and Medical Science: A Review

Внешний щит, исчезающий на наших глазах, - открытый главный компьютер. Этот щит практически взломан. В течение часа то же самое случится с остальными пятью. После этого сюда полезут все, кому не лень.

 Действуй своим маячком очень осторожно, - сказал Стратмор.  - Если Северная Дакота заподозрит, что мы его ищем, он начнет паниковать и исчезнет вместе с паролем, так что никакая штурмовая группа до него не доберется. - Все произойдет, как булавочный укол, - заверила его Сьюзан.  - В тот момент, когда обнаружится его счет, маяк самоуничтожится. Танкадо даже не узнает, что мы побывали у него в гостях.
