Isolation of chitin from the shell of the cuttlefish, Sepia officinalis L.
1.
1. A method is described for isolating flat pieces of transparent, unhydrolysed, protein-free chitin from the shell of the cuttlefish, Sepia officinalis L.
2.
2. Chitin from the dorsal cover and the septa regions of the shell were found to be identical in physical and chemical properties. X-ray studies and, for the first time, infrared spectra, confirm that Sepia chitin is of the β-type.
