... is periodically shed and regenerated during the molt cycle, molar mineral deposition takes place during the pre-molt stage. The molar mineral composition transforms continuously from fluorapatite through amorphous calcium phosphate to amorphous calcium carbonate and is mounted on chitin. The process of crayfish...

...Gunnar Broehan; Lars Zimoch; Anton Wessels; Beyhan Ertas; Hans Merzendorfer SUMMARY The chitin portion of the peritrophic matrix in the midgut of the tobacco hornworm, Manduca sexta , is produced by chitin synthase 2 (CHS2), a transmembrane family II glycosyltransferase, located at the apical tips...

...Hans Merzendorfer; Lars Zimoch SUMMARY Chitin is one of the most important biopolymers in nature. It is mainly produced by fungi, arthropods and nematodes. In insects, it functions as scaffold material, supporting the cuticles of the epidermis and trachea as well as the peritrophic matrices lining...

... thickness varied around the wing, with the remigium and the anal fan showing markedly different properties. The membrane was tested for chitin using two methods: a gas pyrolysis/mass spectrometry assay, and a gold-labelled immunoassay specific to chitin. None was detected, and the membrane may consist...

... the sulfide permeability of the root tube. We found that, while the sulfide concentration is less than 1 μmol l −1 in the sea water surrounding the gills, it can be over 1.5 mmol l −1 at a depth of 10–25 cm in sediment beneath tubeworm bushes. The root tube is composed primarily of giant β-chitin crystallites...
