Enzymatic Modifications of Chitin, Chitosan, and Chitooligosaccharides [PDF]
Frontiers in Bioengineering and Biotechnology, 2019 Chitin and its N-deacetylated derivative chitosan are two biological polymers that have found numerous applications in recent years, but their further deployment suffers from limitations in obtaining a defined structure of the polymers using traditional ...

Advances in chitooligosaccharides chemical modifications [PDF]
Biopolymers, 2021 AbstractChitooligosaccharides (COS) differ from chitosan by their molar mass: those of COS are defined to be lower than 20 kg mol−1. Their functionalization is widely described in the literature and leads to the introduction of new properties that broaden their application fields.

Research Progress on Preparation and Efficacy of Chiooligosaccharide Complex
Shipin gongye ke-ji, 2022 Chitooligosaccharides are the only basic oligosaccharides in nature with -NH2 and -OH functional groups. They are easily soluble in water and have extremely high biological activities such as antibacterial, anti-inflammatory, anti-oxidant, and anti ...

Bioproduction of Chitooligosaccharides: Present and Perspectives [PDF]
Marine Drugs, 2014 Chitin and chitosan oligosaccharides (COS) have been traditionally obtained by chemical digestion with strong acids. In light of the difficulties associated with these traditional production processes, environmentally compatible and reproducible production alternatives are desirable.

Determination of the Deacetylation Degree of Chitooligosaccharides [PDF]
Marine Drugs, 2017 The methods for determination of chitosan content recommended in the Chinese Pharmacopoeia and the European Pharmacopoeia are not applicable for evaluation of the extent of deacetylation (deacetylation degree, DD) in chitooligosaccharides (COS). This study explores two different methods for assessment of DD in COS having relatively high and low ...
