<p>Heparin is a glycosaminoglycan which is a complex carbohydrate that contains repeating disaccharide units of glucosamine and N-acetylglucosamine. Heparin has been shown to inhibit the activity of bacterial enzymes involved in fibrinolysis, such as plasminogen activator inhibitor 1 (PAI-1), and may act as an anticoagulant. Heparin is often used as an anticoagulant in patients with thrombotic disorders, including deep vein thrombosis, pulmonary embolism, or heart attack. Heparin also acts as a cofactor for the activation of clotting factors II (thrombin), VII, IX, X, XI and XII. In addition, it inhibits the activation of factor XIII by preventing its conversion from its inactive form into active factor XIIIa. The molecular weight of heparin is approximately 10 kilodaltons (kDa) and it has a molecular formula</p>

<p>4-O-(b-D-Mannopyranosyl)-D-glucose is a metabolite of D-mannose. It is a bacterial metabolite produced by Streptococcus pneumoniae that has been shown to inhibit the growth of bacteria by binding to the 50S ribosomal subunit. 4-O-(b-D-Mannopyranosyl)-D-glucose inhibits bacterial growth by binding to DNA dependent RNA polymerase, thereby preventing transcription and replication. The high frequency of human activity has been shown using a patch clamp technique on human erythrocytes. This active form is metabolized through a number of metabolic transformations, including hydrolysis by esterases or glucuronidases, oxidation by cytochrome P450 enzymes, reduction by glutathione reductase, or conjugation with glucuronic acid. Rifapentine also specifically binds to markers expressed at high levels in Mycobacter</p>

<p>Chitosan is the deacetylated form of chitin. The polysaccharide is deacetylated in order to render it soluble, which is then possible at pH values of less than 7 (normally in dilute acid). This then allows the material to be used in a number of industrial applications as a binder and film former.</p>

<p>2,3,6,2',3',4',6'-Hepta-O-acetyl-a-D-maltosyl bromide is a fatty acid that is isolated from the fungus Penicillium notatum. It has been shown to have anti-cancer properties by inhibiting cell proliferation and inducing cancer cell death by apoptosis. The mechanism of action has been shown to be due to its ability to inhibit the phospholipid membrane synthesis and disrupt the interaction between lipids and proteins in the membrane. This compound also inhibits the growth of cancer cells by binding with the hydroxyl group on the surface of cancer cells. 2,3,6,2',3',4',6'-Hepta-O-acetyl-a-D-maltosyl bromide has been shown to inhibit muscle cell proliferation in vitro and in vivo. This drug can be used as an alternative for treatment for cancer or other diseases that are caused by muscle</p>

<p>Hyaluronic acid is a glycosaminoglycan found in many organs where it functions as a joint lubricant and shock absorber (Collins, 2006). It is obtained principally from synovial fluid, vitreous humor of the eye, umbilical tissue and cockscomb. The chemical structure of hyaluronic acid is a disaccharide repeat of β-1,3 glucuronic acid and β-1,4 N-acetyl glucosamine (Casu, 1990). Hyaluronic acid is a common ingredient in skin care products and is used as a dermal filler in cosmetic surgery.</p>

<p>6-O-(a-D-[6,6'-2H2]Glucopyranosyl)-D-glucopyranose is a synthetic glycosylation product of 6,6'-dihydroxy-[1,1'-biphenyl]-2H-glycine and D-glucose. The compound is used for the synthesis of oligosaccharides and complex carbohydrates. This product is custom synthesized to meet specific needs and can be modified with methyl groups and fluorination. It has a high purity (≥98%) and CAS number.</p>

<p>Man-7 Glycan is a synthetic, 2-AB labelled fluorinated monosaccharide. It is an oligosaccharide that is synthesized by the glycosylation of mannose and N-acetylglucosamine. This product has been modified with fluorination, methylation, and click chemistry.</p>

<p>This compound is generally known as sucralfate and is a medication for the treatment of active duodenal ulcers. It is also used for the treatment of gastroesophageal reflux disease (GERD) and stress ulcers.  Sucralfate is a sucrose sulfate-aluminium complex that binds to the ulcer, creating a physical barrier that protects the gastrointestinal tract from stomach acid and prevents the degradation of mucus. It also promotes bicarbonate production and acts like an acid buffer with cytoprotective properties.</p>

<p>Agarose is a polysaccharide found in red algae, typically Gelidium and Gracilaria. It is a strictly alternating polysaccharide of α-1,3 linked D-galactose and β-1,4 linked L-3,6 anhydrogalactose with occasional sulfation at position 6 of the anhydrogalactose residue. Agaro-oligosaccharides result from cleavage at galactose residues and neoagaro-oligosaccharides from cleavage at 3,6-anhydro residues. Neoagarotetraose is reported to have potential for novel cosmeceuticals.</p>

<p>6-O-(b -D-Galactopyranosyl)-D-glucopyranose, also called allolactose, is a glucose disaccharide with β1-6 glycosidic link, similar to lactose (glucose β1-4 linked). Allolactose is an inducer of the lac operon in E. coli and many other enteric bacteria.</p>

<p>Heparin is a linear sulphated polysaccharide comprising contiguous disaccharide units of a uronic acid and a derivative of 2-amino-2-deoxy-D-glucose. The heparin tetrasaccharide can be obtained from the degradation of heparin with the lyase enzymes isolated from Flavobacterium heparinum, which yields oligosaccharides terminated at the non-reducing end by the unsaturated unit, 4-deoxy-α-L-threo-hex-4-enopyranosyl uronic acid or its 2-0-sulphated derivative. The major product following lyase degradation is the trisulphated derivative DUA-2S + GlcNS-6S (unsaturated disaccharide). Other oligosaccharides such as the tetrasaccharide, illustrated below, can be produced by the lytic degradation of heparin (Moffat, 1991).</p>
