Structural characteristics and hypoglycemic activity of polysaccharides from Coprinus comatus
Publication date: October 2013 Source:Bioactive Carbohydrates and Dietary Fibre, Volume 2, Issue 2 Author(s): Yanfang Liu , Yuan Zhao , Yan Yang , Qingjiu Tang , Shuai Zhou , Di Wu , Jingsong Zhang The effects of grinding process on the extraction of polysaccharide from Coprinus comatus were investigated. The extracts named as CCPF and CCPP were obtained from the fragments and the powder of the C. comatus fruiting bodies, respectively. The comparison on the chemical analysis of CCPF and CCPP showed that reducing particle size could dramatically improve the extract yield and content of polysaccharide fractions, w...

Aggregation behavior of cyclodextrin and cholesterol in simulated human cerebrospinal fluid
This study intended to mimic physiological conditions regarding concentration and temperature. Co-existing aggregated and non-aggregated structures could be detected in the studied cyclodextrin solutions containing cholesterol. It was found that the CSF components may modify the ratio of the substance being in aggregated or non-aggregated form. By tendency it was recorded that the aggregation state of randomly methylated β-cyclodextrin/cholesterol solutions were susceptible to further aggregation in the presence of CSF components, while 2-hydroxypropyl β-cyclodextrin/cholesterol associates were rather subject to de-aggre...

Okara dietary fiber and hypoglycemic effect of okara foods
Publication date: October 2013 Source:Bioactive Carbohydrates and Dietary Fibre, Volume 2, Issue 2 Author(s): Fei Lu , Yang Liu , Bo Li Okara is the byproduct of tofu or soymilk production process. The okara used in this paper contains 58.60% total dietary fiber (TDF), 55.63% insoluble dietary fiber (IDF) and 1.91% soluble dietary fiber (SDF). Okara may be considered a good source of dietary fiber for the high fiber content, cheap cost and wide resource. Okara dietary fiber mainly consists of arabinose, galactose, xylose and galacturonic acid, and its molecular weight is from 724kDa to 2081kDa. Replacing 25%, 15% or...

Molecular insight of non enzymatic glycosylation of collagen-therapeutic perspective of dietary carbohydrates
Publication date: October 2013 Source:Bioactive Carbohydrates and Dietary Fibre, Volume 2, Issue 2 Author(s): Jayakumar Gladstone Christopher , Raghava Rao Jonnalagadda , Unni Nair Balachandran Glycosylation is a significant post translational step in biosynthesis of collagen which plays a key role in fibrillogenesis and formation of advanced end glycation product (AEG). Diabetes leads to modification of collagen such as AEG and crosslinking which plays an important role in the pathogenesis of diabetes mellitus. In the present research, molecular strategy is chronicled to understand the in vitro non enzymatic glycat...

Sulphated polysaccharide from the sea cucumber Cucumaria frondosa affect maturation of human dendritic cells and their activation of allogeneic CD4(+) T cells in vitro
Publication date: October 2013 Source:Bioactive Carbohydrates and Dietary Fibre, Volume 2, Issue 2 Author(s): Varsha Kale , Jona Freysdottir , Berit S. Paulsen , Ólafur H. Friðjónsson , Guðmundur Óli Hreggviðsson , Sesselja Omarsdottir Sea cucumbers are used as healthy food, traditional medicine and dietary supplement. Sulphated polysaccharides (sPS) from their body wall possess variety of biological activities; however the immunomodulatory effects of sea cucumber polysaccharides remain unknown. Three sPS fractions were isolated from orange-footed sea cucumber (Cucumaria frondosa) and their effects on DC ma...

Effect of the temperature on the degradation of β-glucan promoted by iron(II)
Publication date: October 2013 Source:Bioactive Carbohydrates and Dietary Fibre, Volume 2, Issue 2 Author(s): Audrey M. Faure , Raphael Knüsel , Laura Nyström Cereal β-glucan is a soluble dietary fiber and a versatile functional food ingredient, which is known to be degraded during food processing non-enzymatically. The degradation of β-glucan induced by iron(II) was investigated at different temperatures (25, 50 and 100°C) in pure β-glucan solution. Increasing the temperature of storage enhanced the formation of hydroxyl radical induced by iron(II), hence causing more intense β-glucan degradation. β-Glucan ...

The research legacy of Peter J. Wood
Publication date: October 2013 Source:Bioactive Carbohydrates and Dietary Fibre, Volume 2, Issue 2 Author(s): Susan M. Tosh Peter Wood was an exceptional scientist who helped lay the foundation for our understanding of the health benefits of soluble fiber. As a carbohydrate chemist, he developed methods to characterize polysaccharides and used them to better understand the structure and behavior of cereal (1→3)(1→4)-β-d-glucans. With collaborators, he demonstrated the distribution of these mixed linkage β-glucans in cereal grains and food products. He studied the behavior of β-glucans in solution and demonstrat...

The story of “Hyaluronan Putty”
Publication date: October 2013 Source:Bioactive Carbohydrates and Dietary Fibre, Volume 2, Issue 2 Author(s): Endre A. Balazs , Jennifer Cui Hyaluronic Acid (HA) or hyaluronan displays remarkable properties of elasticity and water retention at a specific and narrow pH range of 2.4–2.6. The behavior and mechanical properties have been characterized using a variety of methodologies including ultracentrifuge sedimentation, rheometry, rate and extent of diffusion, and NMR. Various explanations have been presented in order to explain the phenomenon, including reaching the isoelectric point by manipulating pH, strong cha...

Publication date: October 2013 Source:Bioactive Carbohydrates and Dietary Fibre, Volume 2, Issue 2 Author(s): Floor Hugenholtz , Jane Adair Mullaney , Michiel Kleerebezem , Hauke Smidt , Douglas Ian Rosendale This review considers fermentable carbohydrates and their role in maintaining health through their availability as fuel for the gut microbiota. The microbiota possesses remarkably diverse function, and is likely modifiable by diet. Therefore a diet rich in varied fermentable carbohydrates such as dietary fibre, glycosylated polyphenolics, glucosinolates and other plant glycans, applied in a sustained fashion ...

Oxygen radical absorbance capacity (ORAC) and ferric reducing antioxidant power (FRAP) of β-glucans from different sources with various molecular weight
This study assessed oxygen radical absorbance capacity (ORAC) and ferric reducing antioxidant power (FRAP) of oat β-glucans with different molecular weight (MW). ORAC and FRAP of β-glucans from different sources (oat, yeast, and fungi Schizophyllum commune) were also evaluated. ORAC and FRAP values of β-glucans were significantly different not only among different MW but also among samples from different sources. β-Glucan from brewer's yeast extract with 0.2kDa MW had the highest value of ORAC. Carboxymethyl yeast β-glucan C90 with 404kDa MW exhibited the strongest FRAP values. As for β-glucans with different MW, 180...
