WebFor chitin the solubility parameter (δ) is 12.5, for the chitin-LiCl complex, d~11.2. Two good amide polymer solvents (a polymer solvent is a solvent with the approximately the same solubility parameter as the polymer) are dimethyl-acetamide (δ=10.8) and N-methyl pyrrolidinone (δ=11.3) [2]. WebA thick cell wall made of chitin surrounds the cell. Fungi can be unicellular as yeasts, or develop a network of filaments called a mycelium, which is often described as mold. Most species multiply by asexual and sexual reproductive cycles and display an alternation of generations. Such fungi are called perfect fungi.
WebSome insects are colourful with soft body structure like butterflies, moths, ladybird, dragon flies etc. While others have an hard covering, exoskeleton composed of chitin.
