Oligosaccharides

Isoprimeverose is a covalently linked polysaccharide with a molecular weight of about 5,000. It has been shown to have an optimum pH at around 7.5 and is soluble in water. Isoprimeverose was found to be highly immunogenic in rats and mice, producing high levels of polyclonal antibodies against the protein target. The carbohydrate moiety of isoprimeverose contains galacturonic acid, which may play a role in its uptake by mammalian cells. The hydroxyl group on the sugar molecule may also play a role in this process. Isoprimeverose can be used as an artificial sweetener because it does not contain any sugars or carbohydrates that can cause tooth decay or other dental problems.

SSEA-4 hexaose is a virulence factor that belongs to the lectin family. It has been shown to be activated by binding to lectins, which are proteins that bind carbohydrates. SSEA-4 hexaose has also been shown to have cytotoxic effects on cells and induce apoptosis in some cancer cell lines. This glycan is expressed in many tissues, including brain, heart, liver, kidney, erythrocytes, lymphocytes and monocytes. In addition, it binds specifically to clostridium perfringens and mycobacterium tuberculosis with high affinity.

Mixed DP 10-15 Na galacturonans (α-1,4 10-15 Na galacturonans) are derived from pectin or pectic acid, by enzymatic or partial acid hydrolysis. They are used in galacturonic acid metabolism research as a substrate to identify, differentiate, and characterize endo- and exopolygalacturonase(s) and gluconase(s). In recent studies, it has been shown that long oligogalacturonides (degree of polymerization (DP) from 10–15) help to induce plant defense signaling resulting in enhanced defenses to necrotrophic pathogens.

Non-reducing storage and transport sugar in woody plants; used as a sweetener

D-Celloheptaose is a modified glycosylated oligosaccharide. It is synthesized by the methylation of D-cellotriose with 3-aminopropyl-trimethoxysilane and the subsequent reaction with bromoethanol. The product is purified by fractional crystallization from methanol to give a white crystalline solid. This product has CAS No. 52646-27-2 and is soluble in methanol, ethanol, water, acetone and chloroform.
