Chitin

Chitin a chemical name Poly [? - (1? 4)-2-acetamido-2-deoxy-D-glucopyranose] is a structural biological materials.
Similar to cellulose. But differs by the position C-2 will consist of cellulose hydroxyl group Silk. Will consist of chitin.
A group Citadines Mido (acetamido group), chitin is not soluble in polar solvents, and no poles. In general, chitin is usually found.
In the cell wall of microorganisms such as fungi and insects, and shells of invertebrate types, and there is an articulation
Such as shrimp, crab and squid axis of chitosan or chitin derivatives to be removed from the reaction among Acetylation of chitin million, or at
Called the reaction deacetylation. By immersion of chitin in concentrated alkaline solution. The chitosan has this The chemical name.
poly [? - (1? 4)-2-amino-2-deoxy-D-glucopyranose] is a polymer that can not be dissolved in organic solvents.
Almost all the water and the pH of neutral or alkaline. But can be dissolved in acid.
