2-Allyloxycarbonylamino-2-deoxy-D-galactose is a monosaccharide that is synthetically modified for use as a synthetic building block in the synthesis of complex carbohydrates and saccharides. This compound is fluorinated at the 2 position to increase its water solubility, which makes it useful for chemical modifications. It has been shown to be methylated and glycosylated.

a-D-Glucuronic acid-1-phosphate is a substrate for alkaline phosphatase. It hydrolyzes phosphate esters and modifies inorganic phosphate, including pyrophosphate. It also catalyzes the hydrolysis of nucleotide monophosphates such as NADPH and UDPglucose to their respective diphosphates. This enzyme is not inhibited by inorganic phosphate, phosphatase, NADP+, or UDP-.

Propofol-4-Hydroxy-1-D-glucuronide is a modification of propofol, which is commonly used as an intravenous anesthetic. It is a synthetic compound that can be custom synthesized by adding the sugar group to propofol. Propofol-4-Hydroxy-1-D-glucuronide has been shown to be a high purity and pure oligosaccharide with a CAS number. It also contains methylated and glycosylated saccharides.

Starch consists of two polysaccharides, amylose and amylopectin and represents approximately 20-25% of the total polysaccharide content in starch. Amylose molecules consist of single mostly unbranched chains of 500-20,000 α-(1->4)-D-glucose residues dependent on source (e.g. wheat, rice, potato, tapioca, etc). Amylose can form an extended shape (hydrodynamic radius 7-22 nm) but generally tends to wind up into a rather stiff left-handed single helix or form even stiffer parallel left-handed double helical junction zones. Hydrogen bonding between aligned chains causes retrogradation and releases some of the bound water (syneresis). The aligned chains may then form double stranded crystallites that are resistant to amylases. These possess extensive inter- and intra-strand hydrogen bonding, resulting in a fairly hydrophobic structure of low solubility. The amylose content of starches is thus the major cause of resistant starch formation.

Bearberry has been used for centuries to treat various disorders of the urinary tract and prostate. The active ingredient in bearberry is a flavonol glycoside called arbutin, which is converted to hydroquinone during metabolism. As an antioxidant, hydroquinone inhibits the oxidation of LDL cholesterol and may reduce the risk of atherosclerosis. Hydroquinone has also been shown to have anti-inflammatory properties in rat liver microsomes and tissue culture, inhibiting prostaglandin synthesis by blocking cyclooxygenase activity. In vitro, bearberry extracts have been shown to inhibit bacterial growth on agar plates with pH levels from 4-7 and at concentrations between 0.1-1%. It was found that bearberry extracts were most effective against Pseudomonas aeruginosa strains, with MIC values ranging from 2-4 mg/mL. Bearberry extract was observed to be more effective than ampicillin against these strains in a chromatographic assay.

This beta-cyclodextrin (β-CD) derivative is a functionalized cyclic oligosaccharide composed of seven glucose units, characterized by a hydrophilic exterior and a lipophilic cavity (bigger than α-CD and smaller than γ-CDs), which allows it to encapsulate various guest molecules. This structural feature facilitates its use in multiple applications, including pharmaceuticals, food enhancement, and cosmetics. In the pharmaceutical industry, it enhances the solubility and stability of poorly water-soluble drugs, improving their bioavailability and efficacy while also masking unpleasant tastes. The food sector utilizes it as a stabilizer for flavors, colors, and nutrients, extending shelf life by protecting sensitive ingredients from degradation. In cosmetics, it serves as a complexing agent for fragrances and active components, ensuring their stability and controlled release. Its use expands to many other fields, including nanotechnology for drug delivery systems, environmental remediation for extracting organic pollutants, textiles for slow-release fragrances, and analytical chemistry for chiral separation.

L-Gluconic acid calcium salt is a white crystalline powder. It is soluble in water and slightly soluble in alcohol. The structure of this compound has not been fully elucidated, but it is known to be a modification of L-gluconic acid, which is a monosaccharide. This product can be used as a biochemical reagent for the synthesis of oligosaccharides and polysaccharides.

(-)-isolariciresinol-2a-O-b-D-xylopyranoside is a methylated saccharide that is used in the synthesis of complex carbohydrates. It is synthesized by reacting an aldehyde with an alcohol, and it has been modified using click chemistry. The product is purified to be at least 98% pure, and it can be custom synthesized to order. (-)-isolariciresinol-2a-O-b-D-xylopyranoside can be fluorinated for use as a fluorescent probe for various applications. It has a CAS number of 564964-92-1.
