Oligosaccharides

1,4-beta-D-xylohexaose is a sugar that belongs to the group of xylooligosaccharides. It is an enzymatic inactivator that binds to the enzyme hydrolase family. Xylooligosaccharides are found in plant cell walls, where they can be used as a carbon source by termites. 1,4-beta-D-xylohexaose has been shown to be most active against neutral ph, but it is not active against acidic ph. The enzyme hydrolase family is inhibited by binding with 1,4-beta-D-xylohexaose and this prevents hydrolysis of carbohydrates, which includes glycosidic bonds.br>br> 1,4-beta-D-xylohexaose has also been shown to be beneficial for sustainable agriculture practices as it inhibits enzymes that break down xylooligosaccharides

<p>Lactose is the principal sugar in human and most other mammalian milks, ( 4-O-(β-d-galactopyranosyl)-d-glucopyranose) (Collins, 2006). Lactose undergoes mutarotation; it is a reducing sugar and is significantly less soluble in water than sucrose. Lactose is much less sweet than sucrose (at ~1% about 0.15 (sucrose=1). The enzyme lactase (β-galactosidase), which is present in the small intestine, catalyzes hydrolysis of lactose to form glucose and galactose. Anhydrous lactose is an excipient, filler, diluent, and bulking agent in a wide variety of pharmaceutical tablets, capsules, powders and other preparations. Lactose also has applications as a nutrient and multi-functional ingredient in infant formulae, geriatric, dietetic and health foods (Linko, 1982).</p>

<p>2'-O-Fucosyllactulose is a modified carbohydrate that has been synthesized from a natural source. It is an oligosaccharide that contains the monosaccharide, fucose. This product can be used in the synthesis of polysaccharides and glycosylation reactions. 2'-O-Fucosyllactulose has been methylated, fluorinated, and glycosylated, which makes it suitable for use as a sugar in biotechnology applications.</p>

<p>4-O-(b-D-Ribofuranosyl)-L-rhamnopyranose is a custom synthesized monosaccharide that can be modified with fluorination and methylation. This sugar can be used for glycosylation reactions to form oligosaccharides or polysaccharides. The number of sugar molecules that are attached to the sugar determines the complexity of the carbohydrate. 4-O-(b-D-Ribofuranosyl)-L-rhamnopyranose is an example of a complex carbohydrate because it has four sugars attached to it.</p>

<p>Hybrid Glycan, 2-AB labelled is a custom synthesis of a high purity glycosylation product. This synthetic oligosaccharide includes saccharides that are labelled with 2-AB. The modification is Click chemistry and provides a method for attaching the label to the sugar molecule. This product is not found in nature or existing in cells or organisms. It is used as a research tool in immunology, cell biology, and structural biology applications.</p>

Xylopentaose is a pentose sugar that belongs to the group of polyols. It has been shown to be a dietary supplement that improves the lipid profile in mice and humans, which may be due to its ability to inhibit diacylglycerol acyltransferase, thereby preventing the synthesis of triglycerides. Xylopentaose is also able to increase serum glucose levels by stimulating insulin secretion through the activation of pancreatic β-cells. Xylopentaose can be used as a sweetener because it has some sweetness but does not cause tooth decay like sugar does.

<p>D-Melibiose monohydrate is a type of sugar that can be found in the extracellular space. It is also a component of fatty acids and has been shown to act as a growth factor for some cell types. D-Melibiose monohydrate has been characterized using tissue culture, growth factor profiles, and fluorescence detector. This sugar can be used as an alternative to trehalose in vitro assays, where it has been shown to have similar biological properties. D-Melibiose monohydrate may also be used for the manufacture of solid dispersions due to its solubility in organic solvents.</p>

<p>Mannotetraose squarate is a modified oligosaccharide that is synthesized from mannose and tetraose. It has high purity, which is an advantage over natural oligosaccharides, and can be used in the synthesis of other carbohydrates. Mannotetraose squarate has a CAS number of 385842-90-0, which can be found on the ChemSpider database.</p>

N,N',N''-Triacetylchitotriose is a chiral compound that is formed from the acetylation of chitin. It has been shown to be an antigen for monoclonal antibodies and a model system for exploring the enzymatic hydrolysis of chitin. N,N',N''-Triacetylchitotriose can be used to investigate the catalytic mechanism of chitinase enzymes, which are involved in breaking down the polysaccharide chitin. It has also been shown to have bioactive properties, such as inhibiting lectins and binding with mannose receptors.

Trehalose is a naturally occurring disaccharide found in many organisms. Its role in nature is as versatile as its applications in the laboratory. Trehalose is synthesised by cells in response to stress and helps retaining the cellular integrity under tough conditions. An important function of trehalose is to stabilise protein structures and to prevent proteins from their degradation. Researchers use trehalose for instance as a carbon source in selective microbiological media, as desiccation protectant and for cryoprotection.

<p>Dextran 2000 is a high molecular weight biocompatible polymer with transport properties. It is used in a variety of medical applications, such as red blood cell transfusions and the prevention of post-surgical adhesions. Dextran 2000 has been shown to be a safe and effective means of preventing hemolysis during red blood cell transfusion. This agent binds to amine groups on the surface of erythrocytes, which prevents complement activation and subsequent lysis. Additionally, dextran 2000 has been shown to exhibit low cytotoxicity against neuronal cells in vitro.</p>

<p>Cellobiose is a reducing disaccharide consisting of two β(1-4)-linked glucopyranose units. It is produced by the hydrolysis of cellulose, a homopolysaccharide of glucose with β(1-4)-linkages. Cellobiose constitutes the polar part of cellobiose lipids (CLs) that are secreted by yeasts and mycelia fungi. Their various biological activities have led to a range of applications in the food industry, pharmaceutical industry and in medicine. Cellobiose itself has been used as an indicator carbohydrate for Crohn’s disease and malabsorption syndrome.
