Carbohydrates, including polysaccharide macromolecules, are the main constituents of fungal cell wall. Among these, homo- or heteropolymeric glucan molecules decisive, as they not only protect cells but also have broad, positive biological effects on animal and human bodies. In addition to beneficial nutritional properties mushrooms (mineral elements, favorable proteins, low fat energy content, pleasant aroma, flavor), a high content. Folk medicine (especially in Far East) used medicinal based previous experience. At end 19th century, mainly since middle 20th progressively more scientific information has been published. Glucans from polysaccharides that contain sugar chains, sometimes one kind (glucose), having several monosaccharide units, two (α β) anomeric forms (isomers). Their molecular weights range 104 105 Da, rarely 106 Da. X-ray diffraction studies were first determine triple helix configuration some glucans. It seems existence integrity structure criteria for their effects. Different glucans can be isolated different mushroom species, fractions obtained. The biosynthesis takes place cytoplasm, processes initiation then chain extension take with help synthase enzyme complex (EC 2.4.1.34), units provided by donor UDPG molecules. methods today determination enzymatic Congo red methods. True comparisons made using same method. dye reacts tertiary structure, resulting content better reflects value effect β-glucan is proportional structure. contents stipe exceed values caps. levels individual taxa (including varieties) differ quantitatively qualitatively.

Effects of in vitro digestion and fecal fermentation on physico-chemical properties and metabolic behavior of polysaccharides from Clitocybe squamulosa

Food Chemistry X, Год журнала: 2023, Номер 18, С. 100644 - 100644

The aim of this study was to establish a human digestion model in vitro explore the degradation characteristics novel high-purity polysaccharide from Clitocybe squamulosa (CSFP2). results showed that content reducing sugars (CR ) CSFP2 increased 0.13 0.23 mg/mL, molecular weight (Mw) decreased significantly during saliva-gastrointestinal digestion. constituent monosaccharides CSFP2, including galactose, glucose, and mannose, were stable digestion, but their molar ratios changed 0.023: 0.737: 0.234 0.496: 0.478: 0.027. surface changes rough flaky structure scattered flocculent or rod-shaped after gastrointestinal However, apparent viscosity overall Moreover, still maintains its strong antioxidant capacity can be partially decomposed Meanwhile, some physico-chemical properties fermentation broth containing gut microbiota fermentation. For example, pH value (from 8.46 4.72) (p < 0.05) 48 h OD600 first then 2.00 2.68 1.32) 48-h In addition, could also increase amounts short-chain fatty acids (SCFAs) 5.5 37.15 mmol/L) (in particular, acetic acid, propionic butyric acid). Furthermore, relative abundances Bacteriodes, Bifidobacterium, Catenibacterium, Lachnospiraceae_NK4A136_group, Megasphaera, Prevotella, Megamonas, Lactobacillus at genus level markedly with intervention CSFP2. These provided theoretical basis for further development functional foods related

Antioxidant activities of sea buckthorn polysaccharides and their potential application in cosmetic industry

Many natural polysaccharides have been reported to protect against skin aging through antioxidant pathways, but sea buckthorn less well studied in terms of activity, and the related studies are not developed. By examining chemical structure polysaccharides, this research aimed offer a scientific foundation for their use cosmetics explore vitro potential these polysaccharides. Methods: We made SP (sea crude polysaccharide) using both hot water extraction ultrasonic extraction. Then, we used anion exchange method separate purify it get three different polysaccharides: SPA (polysaccharide eluted from deionized water), which is neutral polysaccharide, SPB (polysaccharides 0.1 M NaCl) SPC 0.2 NaCl), acidic The characteristics four (SP, SPA, SPC) were determined high-performance gel permeation chromatography (HPGPC), liquid (HPLC), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), x-ray diffractometry (XRD). In assays test activities. assay showed that SPB, good at getting rid superoxide DPPH radicals, especially ABTS radicals. They also better free radicals than VC low concentrations, they reducing other molecules. These results polysaccharide has certain activity; therefore, strong be applied anti-aging functional cosmetics.
