a complex polysaccharide molecule found in walls of fungi and exoskeletons of shrimps and crabs
White, horny substance found in the external skeleton of crabs, lobsters, and many insects; in internal structures of some other invertebrates; and in some fungi, algae, and yeasts. It is a polysaccharide, the monomer unit being glucosamine. It is used industrially in purifying wastewater, thickening and stabilizing foods and pharmaceuticals, and sizing and strengthening paper, and as a wound-healing agent, an ion-exchange resin, a membrane for industrial separations, and a binder for dyes, fabrics, and adhesives
a polysaccharide, the principal constituent of shells of arthropods and shards of beetles, and found in certain fungi
A complex polysaccharide, a polymer of N-acetylglucosamine, found in the exoskeletons of arthropods and in the cell walls of fungi; thought to be responsible for some forms of asthma in humans
a tough semitransparent horny substance; the principal component of the exoskeletons of arthropods and the cell walls of certain fungi
A structural polysaccharide of an amino sugar found in many fungi and in the exoskeletons of all Arthropods
