The Chitin Connection
Chitin, a polymer of N-acetylglucosamine, is an essential component of the fungal cell wall. Chitosan, a deacetylated form of chitin, is also important in maintaining cell wall integrity and is essential for Cryptococcus neoformans virulence. In their article, Gilbert et al. [N. M. Gilbert, L. G. Baker, C. A. Specht, and J. K. Lodge, mBio 3(1):e00007-12, 2012] demonstrate that the enzyme respon...
متن کاملChitin Nanowhisker Aerogels
Chitin nanowhiskers are structured into mesoporous aerogels by using the same benign process used previously in our group to make cellulose nanowhisker aerogels. The nanowhiskers are sonicated in water to form a hydrogel before solvent-exchange with ethanol and drying under supercritical CO2 (scCO2 ). Aerogels are prepared with various densities and porosities, relating directly to the initial ...
متن کاملTotally tubular chitin
Totally tubular chitin lies create uniform tracheal tubes by molding them around an expanding chitin filament, according to Anna Tonning, Anne Uv, and colleagues (Göteborg University, Göteborg, Sweden). Uv’s group suspected that chitin may be involved in shaping tracheal tubes after observing that a chitin synthase mutant forms tracheal branches that look like sausages rather than uniform cylin...
متن کاملChitin Research Revisited
Two centuries after the discovery of chitin, it is widely accepted that this biopolymer is an important biomaterial in many aspects. Numerous studies on chitin have focused on its biomedical applications. In this review, various aspects of chitin research including sources, structure, biosynthesis, chitinolytic enzyme, chitin binding protein, genetic engineering approach to produce chitin, chit...
متن کاملChitin and Chitosan: Structure, Properties and Applications
Chitin and chitosan are the most abundant natural amino polysaccharide that are non-toxic, biodegradable and biocompatible. They have become of great interest not only as an underutilized resource, but also as a new functional material of high potential in various fields. They are biopolymers having immense structural possibilities for chemical and mechanical modifications to generate novel pro...
