Scleroglucan
Schizophyllan (Sonifilan, SPG) is a neutral extracellular polysaccharide produced by the fungus ''Schizophyllum commune''. Schizophyllan is a β-1,3 beta-glucan with β-1,6 branching. Schizophyllan is also known as sizofiran. Schizophyllan has a molecular weight of 450,000 Da, and a specific rotation in water of +18-24°. A chemically analogous polysaccharide, scleroglucan, is formed by the fungus ''Athelia rolfsii''. Both polysaccharides share the chemical structure of the backbone with curdlan. It is known for several things, including its ability to stimulate the immune system, carry metals in water, aid in delivering drugs, and use in some nanofibers. Safety Schizophyllan, classified as a beta-glucan and extracted from the fungus ''Schizophyllum commune'', showed no quantifiable adverse reactions through independent scientific procedures. With its classification as a beta-glucan, schizophyllan is generally recognized as safe (GRAS) by the United States FDA. While no distinct ...

Polysaccharide
Polysaccharides (), or polycarbohydrates, are the most abundant carbohydrates found in food. They are long chain polymeric carbohydrates composed of monosaccharide units bound together by glycosidic linkages. This carbohydrate can react with water (hydrolysis) using amylase enzymes as catalyst, which produces constituent sugars (monosaccharides, or oligosaccharides). They range in structure from linear to highly branched. Examples include storage polysaccharides such as starch, glycogen and galactogen and structural polysaccharides such as cellulose and chitin. Polysaccharides are often quite heterogeneous, containing slight modifications of the repeating unit. Depending on the structure, these macromolecules can have distinct properties from their monosaccharide building blocks. They may be amorphous or even insoluble in water. When all the monosaccharides in a polysaccharide are the same type, the polysaccharide is called a homopolysaccharide or homoglycan, but when more t ...

Schizophyllum Commune
''Schizophyllum commune'' is a species of fungus in the genus ''Schizophyllum''. The mushroom resembles undulating waves of tightly packed corals or loose Chinese fan. "Gillies" or "split gills" vary from creamy yellow to pale white in colour. The pileus (mycology), cap is small, wide with a dense yet spongey body texture. It is known as the split-gill mushroom because of the unique longitudinally divided nature of the "lamella (mycology), gills" on the underside of the cap. This mushroom is found throughout the world. It is found in the wild on decaying trees after rainy seasons followed by dry spells where the mushrooms are naturally collected. It is known for its high medicinal value and aromatic taste profile. It has recently attracted the medicinal industry for its immunomodulatory, antifungal, antineoplastic and antiviral activities that are higher than those of any other glucan complex carbohydrate. Description ''Schizophyllum commune'' is usually described as a morpholog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beta-glucan
Beta-glucans, β-glucans comprise a group of β-D-glucose polysaccharides ( glucans) naturally occurring in the cell walls of cereals, bacteria, and fungi, with significantly differing physicochemical properties dependent on source. Typically, β-glucans form a linear backbone with 1–3 β-glycosidic bonds but vary with respect to molecular mass, solubility, viscosity, branching structure, and gelation properties, causing diverse physiological effects in animals. At dietary intake levels of at least 3 g per day, oat fiber β-glucan decreases blood levels of LDL cholesterol and so may reduce the risk of cardiovascular diseases. β-glucans are natural gums and are used as texturing agents in various nutraceutical and cosmetic products, and as soluble fiber supplements. History Cereal and fungal products have been used for centuries for medicinal and cosmetic purposes; however, the specific role of β-glucan was not explored until the 20th century. β-glucans were first discov ...

Athelia Rolfsii
''Athelia rolfsii'' is a corticioid fungus in the family Atheliaceae. It is a facultative plant pathogen and is the causal agent of "southern blight" disease in crops. Taxonomy The species was first described in 1911 by Italian mycologist Pier Andrea Saccardo, based on specimens sent to him by Peter Henry Rolfs who considered the unnamed fungus to be the cause of tomato blight in Florida. The specimens sent to Saccardo were sterile, consisting of hyphae and sclerotia. He placed the species in the old form genus ''Sclerotium'', naming it ''Sclerotium rolfsii''. It is, however, not a species of ''Sclerotium'' in the strict sense. In 1932, Mario Curzi discovered that the teleomorph (spore-bearing state) was a corticioid fungus and accordingly placed the species in the form genus '' Corticium''. With a move to a more natural classification of fungi, ''Corticium rolfsii'' was transferred to '' Athelia'' in 1978. Description The fungus produces effused basidiocarps (fruit bodies) th ...

Curdlan
Curdlan is a water-insoluble linear beta-1,3-glucan, a high-molecular-weight polymer of glucose. Curdlan consists of β-(1,3)-linked glucose residues and forms elastic gels upon heating in aqueous suspension (chemistry), suspension. It was reported to be produced by ''Alcaligenes faecalis'' var. ''myxogenes''. Subsequently, the taxonomy of this non-pathogenic curdlan-producing bacterium has been reclassified as ''Agrobacterium'' species. Extracellular and capsular polysaccharides are produced by a variety of pathogenic and soil-dwelling bacteria. Curdlan is a neutral β-(1,3)-glucan, perhaps with a few intra- or interchain 1,6-linkages, produced as an exopolysaccharide by soil bacteria of the family Rhizobiaceae. Four genes required for curdlan production have been identified in ''Agrobacterium'' sp. ATCC31749, which produces curdlan in extraordinary amounts, and ''Agrobacterium tumefaciens''. A putative operon contains crdSQ9X2V0 family GT2, ), encoding β-(1,3)-glucan synthase c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Food And Drug Administration
The United States Food and Drug Administration (FDA or US FDA) is a List of United States federal agencies, federal agency of the United States Department of Health and Human Services, Department of Health and Human Services. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco products, caffeine products, dietary supplements, Prescription drug, prescription and Over-the-counter drug, over-the-counter pharmaceutical drugs (medications), vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices (ERED), cosmetics, Animal feed, animal foods & feed and Veterinary medicine, veterinary products. The FDA's primary focus is enforcement of the Federal Food, Drug, and Cosmetic Act (FD&C), but the agency also enforces other laws, notably Section 361 of the Public Health Service Act, as well as associated regulations. Much of this regulatory-enforcement work is not d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
