WebChitin is a homopolymer of β1-4-linked GlcNAc synthesized by chitin synthase. The presence of chitin in nematodes is well documented.41 The C. elegans genome has two … WebThe chitin structure in native environments and cell walls of algae and fungi, for example, is much more complicated than the simplified models, which are determined using high-crystallinity and purified chitin materials. This is due to the complexity of chitin synthesis and the complex environments of chitin and other cell-wall components [12,24].
