Chitin is a natural polymer found in fungi cell wall, exoskeletons of insects, and the shells of crustaceans. The main function of chitin is to provide protection and strength to fragile bodies of these organisms. How is chitin produced? Biosynthesis of chitin involves several catalytic reactions ...
terminaldomain, which are close to the central catalytic region, may function in post-catalytic processes such as translocation of chitin polymers across cell membranes (Cohen, 2001; Merzendorfer, 2006). Sign in to download full-size image

Figure 1. Chitin structure and diversity in fungi. Chitin is a β(1,4)-homopolymer of N-acetylglucosamine that folds in an anti-parallel manner forming intra-chain hydrogen bonds. Chitin chains are cross-linked covalently to β(1,3)-glucan (green) to form the inner skeleton of most fungi...
chitin[ 'kaitin ] n.a tough semitransparent horny substance; the principal component of the exoskeletons of arthropods and the cell walls of certain fungi 学习怎么用 双语例句 用作名词(n.) The exoskeleton of insects is largely made of protein and chitin. ...
In addition, chitin also confers rigidity to the cell wall, whereas glycoproteins can function in signal transduction, adhesion, absorption of molecules, protection against unfamiliar substances and synthesis and remodeling of the FCW [2,6]. Preceded only by cellulose, chitin is the second most ...

Review Chitin metabolism in insects: structure, function and regulation of chitin synthases and chitinases. Chitin is one of the most important biopolymers in nature. It is mainly produced by fungi, arthropods and nematodes. In insects, it functions as scaffold m... Merzendorfer,Hans,Zimoch,.....
In the tissue engineering, it can be used for manufacturing polymer scaffold to satisfy the demands of repairing, replacing, maintaining, or enhancing the function of a particular tissue or organ. In wound dressing, chitin can be used as antimicrobial reagent. In the field of drug delivery, ...
elegans as a model to address their functions in nematodes. We probed the function of chitin synthases by knocking down individual chitin synthase transcripts with RNAi and by GFP transcription reporter analysis. We also examined the localization of chitin in different tissues of wild type worms ...
