Glucomannan is a soluble, highly viscous fiber commonly derived from Amorphophallus konjac root. Glucomannan has no specific lactation-related uses. It is most often used to lower cholesterol, to treat constipation and diabetes, and is contained in …

Glucomannan is a water-soluble polysaccharide that is considered a dietary fiber. It is a hemicellulose component in the cell walls of some plant species. Glucomannan is a food additive used as an emulsifier and thickener. It is a major source of mannan oligosaccharide (MOS) found in nature, the other being galactomannan, which is insoluble. [1]

Chemical structure of glucomannan. Macroscopically, Konjac glucomannan is a soluble, fermentable, and highly viscous fiber, which is traditionally also used for culinary purposes in Japan and China. It is claimed that glucomannan preparations promote weight loss, probably by stimulating satiety and/or reducing fat absorption.

The 3D chemical structure image of Glucomannan is based on the ball-and-stick model which displays both the three-dimensional position of the atoms and the bonds between them. The radius of the spheres is therefore smaller than the rod lengths in order to provide a clearer view of the atoms and bonds throughout the chemical structure model of ...

Glucomannan is characterized by low crystallinity, high thermostability, and the ability to form a strong gel. Subsequently, glucomannan has good potential for the production of biodegradable ...

2024年11月14日 · The chemical structure of glucomannan consists in an 8:5 mannose:glucose ratio, linked by b-glycosidic bonds, making raw glucomannan the highest molecular weight and viscosity of any other known dietary fibers.

2023年4月12日 · Konjac glucomannan (KGM) is a naturally occurring macromolecular polysaccharide that exhibits remarkable film–forming and gel–forming properties, and a high degree of biocompatibility and biodegradability. The helical structure of KGM is maintained by the acetyl group, which plays a crucial role in preserving its structural integrity.

Due to its complex chemical structure, it possesses attractive properties including, higher aqueous solubility, excellent swelling behaviour, stability over a wide range of pH and eligibility...

... backbone of xylan is xylopyranosyl and the linkage between the units is α-(1→2)-linked 4-O-methylglucoronic acid; glucomannan's backbone is composed of β-(1→4)-linked D-mannose and D ...

2021年1月1日 · Chemical structure of konjac glucomannan. The crystalline form of KGM was studied by X-ray diffraction ( Ogawa, Yui, & Mizuno, 1991 ). KGM shows a different X-ray diffraction powder pattern from both crystalline polymorphs of other glucomannans (mannan I and mannan II), which have been studied ( Ogawa et al., 1991 ).
