polysaccharides

Lipopolysaccharides (LPS) derived from Escherichia coli 055:B5, are a unique component of the cell wall of Gram-negative bacteria. They are composed of three regions: lipid A, oligosaccharide core, and O-specific polysaccharide (O-antigen). Lipopolysaccharides help maintain the integrity of the cell outer membrane and protect bacteria from damage by bile salts and lipid antibiotics. Lipopolysaccharides are highly immunogenic antigens that can enhance immune responses and can be used to construct inflammatory models.

α-L-Rhamnose monohydrate (6-deoxy-L-mannose monohydrate) is a component of bacterial polysaccharides where it plays an important role in pathogenicity.

D-(+)-Xylose (Wood sugar) is an aldopentose - a monosaccharide containing five carbon atoms and an aldehyde functional group. It has chemical formula C5H10O5 and is 40% as sweet as sucrose. Xylose is also found in mucopolysaccharides of connective tissue and sometimes in the urine. Xylose is the first sugar added to serine or threonine residues during proteoglycan type O-glycosylation. Therefore xylose is involved in the biosythetic pathways of most anionic polysaccharides such as heparan sulphate and chondroitin sulphate. In medicine, xylose is used to test for malabsorption by administering a xylose solution to the patient after fasting. If xylose is detected in the blood and/or urine within the next few hours, it has been absorbed by the intestines. Xylose is said to be one of eight sugars which are essential for human nutrition, the others being galactose, glucose, mannose, N-acetylglucosamine, N-acetylgalactosamine, fucose, and sialic acid. . Xylose in the urine is a biomarker for the consumption of apples and other fruits.

D-Galactose (Alpha-D-galactose) is an aldohexose that exists naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins and is converted enzymatically into D-glucose for metabolism or polysaccharides for storage. It accelerates senescence in invertebrates and mammals and has been used as a model for aging.

Lipopolysaccharides, Escherichiacoli (E. coli O111:B4) are derived from Escherichia coli O111:B4 and are a unique component of the cell wall of Gram-negative bacteria. They are composed of three regions: lipid A, oligosaccharide core, and O-specific polysaccharide (O-antigen). Lipopolysaccharides, Escherichiacoli help maintain the integrity of the cell outer membrane and protect bacteria from bile salts and lipid antibiotics.

UDP-g acid is a sugar used in the production of polysaccharides and is an intermediate in the biosynthesis of ascorbic acid

UDP-xylose, a natural product isolated from Cryptococcus laurentii (NRRL Y-1401), serves as a sugar donor in the synthesis of glycoproteins, polysaccharides, various metabolites, and oligosaccharides across plants, vertebrates, and fungi [1] [2].

Lacto-N-difucohexaose I (LNDFH I), a connecting agent, may facilitate the attachment of oligosaccharides bearing Lewis b sugar chains to water-insoluble polysaccharides [1].

Uridine diphosphate glucuronic acid ammonium (UDP-α-D-glucuronic acid ammonium) is a precursor of many plant cell wall polysaccharides and is required for the production of seed mucilage.Uridine diphosphate glucuronic acid ammonium is a precursor of pathogenic fungi. ammonium is a key metabolite for pod polysaccharide synthesis in the pathogenic fungus Cryptococcus neoformans.

Hautriwaic acid shows anti-inflammatory activity in 12-O-tetradecanoylphorbol 13-acetate (TPA) mice ear edema models, it diminishes the joint edema induced by this mixture of polysaccharides (carrageenan), possibly by acting as immunomodulator of the infl

Polypectate sodium, a principal constituent of cell wall polysaccharides (pectins), serves as a carbon source and triggers polygalacturonase production. It is also employed to assess alkaline-active and stable pectate lyases from Streptomyces spp., and to investigate the optimization of polygalacturonase synthesis from Xanthophyllum spp. under various reaction conditions [1].
