摘要

1.1. 本文描述了一种从乌贼(Sepia officinalis L.2.2)壳中分离透明、未水解、无蛋白的扁平几丁质的方法。发现背盖和壳隔区域的几丁质在物理和化学性质上是相同的。x射线研究和红外光谱首次证实了棕褐色几丁质为β型。

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.
