Partially acetylated chito-oligosaccharides (paCOS) have diverse bioactivities that turn them into promising compounds especially for medical and agricultural applications. These properties likely arise from different acetylation patterns, but determining the sequences of paCOS and producing paCOS with patterns of interest have proven difficult.

Supercritical fluid assisted production of chitosan oligomers micrometric powders
Carbohydrate Polymers, 2014Chitosan oligomers (O-chitosan) micrometric particles were produced from aqueous solution using a novel process, i.e. supercritical fluid assisted atomization introduced by hydrodynamic cavitation mixer (SAA-HCM). Hydrodynamic cavitation was introduced to enhance mass transfer and facilitate the mixing between SC-CO2 and liquid solution for fine ...

Kinetics of hydrolysis of chitin/chitosan oligomers in concentrated hydrochloric acid
Carbohydrate Research, 2007The kinetics of hydrolysis in concentrated hydrochloric acid (12.07 M) of the fully N-acetylated chitin tetramer (GlcNAc(4)) and the fully N-deacetylated chitosan tetramer (GlcN(4)) were followed by determining the amounts of the lower DP oligomers as a function of time.

Introduction of a nitrogen heterocycle into sulphated chitosan oligomers
1999Chitin is a linear polysaccharide consisting of [-4) 2-acetamido-2-deoxy-p-Dglucopyranose (1- and -4) 2-amino-2-deoxy P-D-glucopyranose (l-]n which occurs widely in nature and which after further de-//-acetylation yields chitosan. Chitin, chitosan and many of their derivatives have found applications in industry, medicine, pharmacology and food ...
