The oxidized κ-carrageenans with different oxidation levels were prepared through the
hydrogen peroxide and copper sulfate redox system. The oxidation level of oxidized κ …

Κ-carrageenan oligosaccharides were prepared by enzymatic degradation. The inhibiting
activities of the prepared κ-carrageenan oligosaccharides against Escherichia coli (E. coli) …

In the present study, four kinds of κ-carrageenan oligosaccharides were obtained by the
degradation of parent κ-carrageenan using free radical depolymerization, mild acid …

In order to develop a wound healing material possessing anticoagulant activity,
antimicrobial activity and moisture absorbability and moisture-retention capacity …

Abstract κ‐Carrageenan was degraded by an oxidative method involving hydrogen peroxide
(H2O2). The molecular weight was measured by gel permeation chromatography. The …

Chemical modification of polysaccharides is an important route to enhance, develop or
change polysaccharide properties. In this study, carboxymethylation of kappa-carrageenan …

Antioxidant activity of κ-carrageenan oligosaccharides (OM) and their chemical modification
derivatives was investigated employing various established in vitro systems, such as …

Carboxymethyl derivatives of kappa-carrageenan (KC) with varying degrees of substitution
were obtained by multi-step carboxymethylation process. The structural and chemical …

In this paper, carrageenans having distinct sulfation patterns (κ-, ι-, ι/ν-, θ-and λ-
carrageenans), were fully or partially oxidized at C-6 of the β-d-Galp units using 2, 2, 6, 6 …

Degradation of native κ‐carrageenan was performed using acid hydrolysis aided with
microwave heating. Combined with nonofiltration membrane (cut‐off molecular weight 250 …
