A fucan sulphate found in brown marine algae (Phaeophyta-typically Fucus vesiculotus, Ascophyllum nodosum, Alaria and Macrocystis pyrifyra (illustrated) and has been shown to have anticoagulant activity. The main constituents are α-1,4 and α-1,2 linked L-fucose sulphates, although galactose also occurs and there are many variations of the basic structure found in different species of Phaeophyta.
The fucose content of this fucan is approx. 31% and it also contains galactose (approx. 2.2%), uronic acid (approx. 12.4%) and sulfate (approx. 32.5%).

Glycol ethers are compounds that are used as solvents and plasticizers. They have been shown to inhibit the activity of enzymes, such as glucose-6-phosphate dehydrogenase, which is involved in the conversion of glucose to phosphate. Glycol ethers also promote sugar transport by inhibiting the sodium-dependent glucose transporter (SGLT). This transport mechanism is important for maintaining normal blood sugar levels and preventing diabetic neuropathy. Glycol ethers are also anti-diabetic agents that can increase insulin sensitivity by stimulating insulin release from pancreatic beta cells and improving the response of peripheral tissues to insulin stimulation.

Phosphatidyl inositol-10mg/ml solution in chloroform:methanol(4:1) is a carbohydrate that is a complex carbohydrate. It is synthesized by the modification of the phosphatidyl inositol molecule with fluorination and methylation. The CAS number for this compound is 91228-52-5. This product can be custom synthesized as per customer's requirements. It has a high purity and excellent quality, and is available at competitive prices.

Methyl cellulose is a water-soluble polymer that is used as a binder or thickener in pharmaceutical, food, and ceramic processing applications. Methylcellulose has an unusual lower critical solution temperature (LCST) between 40 °C and 50 °C. At temperatures below the LCST it is readily soluble in water; above the LCST it is not soluble, which has a paradoxical effect that heating a saturated solution of methylcellulose will turn it solid, because methylcellulose will precipitate out. The temperature at which this occurs depends on DS-value, with higher DS-values giving lower solubility and lower precipitation temperatures because the polar hydroxyl groups are masked.

3,4,6-Tri-O-acetyl-2-deoxy-2-phthalimido-b-D-glucopyranosyl fluoride is a synthetic glycoside that has been synthesized by the click modification of a fluorinated saccharide. The compound has an acetyl group at C3 and C6 positions with an OCH3 group at the C4 position. This compound has been used in glycosylation reactions to modify the carbohydrate moiety of peptides and proteins. It has also been used in research on complex carbohydrate chemistry.

Synthesized by the action of zinc chloride on tetra-O-acetylmannose and 1-chloro-3,4,6- tri-0-acetylmannose.  Isolated from partial acetolysates of baker's yeast mannan and Saccharomyces rouxii mannan.

2-Formylphenyl b-D-glucopyranoside is a phenolic compound that has been shown to have high resistance to transport. It has been shown to possess surface methodology and this property can be used for the delivery of compounds. 2-Formylphenyl b-D-glucopyranoside has also been shown to inhibit plant enzyme activities such as detoxification enzymes and carbohydrate chemistry, which are important in the uptake of natural compounds. In addition, it is able to bind with amines and hydroxyl groups on cells, which may be due to its receptor cell properties. 2-Formylphenyl b-D-glucopyranoside can be synthesized by reacting trifluoroacetic acid with an amine and a hydroxyl group in the presence of glycol ethers or natural compounds.

2,3:4,5-Di-O-isopropylidene-b-D-fructopyranose (IDFP) is a natural compound that has been shown to have pharmacological properties. It is an inhibitor of the enzyme alpha-glucosidase and may be used as a treatment for diabetes mellitus type II. IDFP binds to the active site of the enzyme α-glucosidase, preventing access of the substrate glucose. This causes a decrease in blood glucose levels and has also been shown to reduce cholesterol levels in mice. IDFP is synthesized by reacting ethylene diamine with 2,3:4,5-di-O-isopropylidene b -D -fructofuranose. This reaction produces a heterocycle that undergoes asymmetric synthesis using sodium hydroxide solution and hydrogen fluoride as catalysts.

2-C-Hydroxymethyl-D-ribose is a sugar that has been found in the cell wall of Mycobacterium tuberculosis. It is also found in some other bacteria, such as Streptomyces coelicolor. 2-C-Hydroxymethyl-D-ribose may be involved in the synthesis of glycan and may have a role in the molybdenum cofactor biosynthesis pathway. This molecule has been shown to have acidic properties, which are most likely due to its hydroxyl groups. The 13C NMR spectrum for this compound shows three peaks at δ H = 138.2, 144.3, and 154.5 ppm corresponding to the ribofuranoside moiety. The skeleton of this molecule was rationalized by attaching an acetaldehyde group to the 2'-hydroxyl group on position C2 of ribose, which is consistent with the observed 13C NMR spectrum. This molecule has
