TLDR
It is concluded that a small but significient number of the amino groups in the chitin molecule are not acetylated, and the molecular packing of the chains was essentially side-by-side.About:

Carboxymethylated chitins and chitosans
TL;DR: The carboxymethylation procedures developed to impart amphoteric properties to chitosan make use of monochloroacetic acid and of glyoxylic acid, respectively, for the preparation of O-carboxyethyl and N-Carboxy methyl chitin, respectively as discussed by the authors.

N-Acetylglucosamine: Production and Applications
TL;DR: This review discusses the industrial production of GlcNAc, using chitin as a substrate, by chemical, enzymatic and biotransformation methods, and newly developed methods to obtain Glc NAc using glucose as a substratum in genetically modified microorganisms are introduced.

Contribution to the preparation of chitins and chitosans with controlled physico-chemical properties
TL;DR: In this paper, an approach on the preparation of chitins and chitosans with controlled physico-chemical characteristics was presented, from many new examples, and the chitin deacetylation was carried out according to two methods using, respectively, as alkaline agent, the aqueous sodium hydroxide solution and anhydrous potassium hyroxide.

Determination of reducing sugar with improved precision.
TL;DR: The replacement of the tartrate chelating agent by glycine reduces the value of the blank and decreases the relative standard error of the conventional oxidation procedure by a factors of approximately 6 at low substrate concentrations and by a factor of 2 at high substrate concentrations.

The Chitin/Protein Complexes of Insect Cuticles
TL;DR: This chapter considers the principal known facts about chitin and the cuticular proteins and gives a description of some new features of the chitIn/protein complex as seen by X-ray analysis.

THE CRYSTAL STRUCTURE OF α-CHITIN (POLY-N-ACETYL-D-GLUCOSAMINE)
TL;DR: The new model of chitin accounts properly for known chemical and physical properties, including the infrared absorption as well as for x-ray data, but because of the limited resolution of the diffraction patterns it can only be regarded as a good approximation.
