WebChitin is well known as a component of insect cuticles, and is a structural polysaccharide in fungal cell walls (reviewed in [ Merzendorfer11] and [ Kramer05 ]). As an essential component of fungal cell walls, chitin biosynthesis during the cell cycle is highly regulated. Because chitin is absent in vertebrates and it appears to have a role in ... WebMay 18, 2024 · Chitin biosynthesis, modification, assembly, degradation, and turnover are highly complex processes in arthropods. Although rapid advances in genomics, proteomics, RNAi, and other technologies have considerably facilitated the research in recent years, many of these processes are still partially understood.
WebJul 24, 2024 · Chitin synthesis inhibitors impede the biosynthesis of chitin. As a result, the cuticle is usually malformed following ecdysis, causing morphological abnormalities or death. Few studies have investigated the efficacy of chitin synthesis inhibitors against bed bugs, and there are currently no insecticides labeled in the United States as ...
