Oligosaccharides

Man-6 Glycan, 2-AB labelled is a custom synthesis of mannose-6-phosphate, a monosaccharide. The molecule contains six carbons and one phosphate group. It can be modified with fluorination, methylation, or click modification. This glycan is synthesized by the addition of an oligosaccharide to a polysaccharide. Mannose-6-phosphate is an Oligosaccharide that carries out glycosylation reactions in the body. It is used as a precursor for other glycans such as N-Acetylglucosamine and N-Acetylgalactosamine.

Monosialyllacto-N-neohexaose is a postulated sugar that has been suggested to be a membrane potential stabilizer. It has been shown to have a linear response in analytical methods, such as mitochondrial membrane potential and glycosidic bond. Monosialyllacto-N-neohexaose has also been investigated for use in diabetic patients because it may help to improve the membrane potential of cells. This sugar has also been studied for use in colostrum and infant formula due to its ability to stimulate the production of TNF-α, which is important for immune system development.

Lacto-N-difucohexaose IV is a pentasaccharide with a lacto-n-difucohexaose backbone that has been shown to have inhibitory activities against human red blood cells. This pentasaccharide is a glycosaminoglycan, which is a type of carbohydrate that consists of an oligosaccharide and protein. Lacto-N-difucohexaose IV specifically binds to the antigen on the surface of human red blood cells, inhibiting their proliferation. The pentasaccharide is also known as Hansson's hapten or Hapten IV. The pentasaccharides are found in group O blood and are not found in groups A, B, or AB.

Lacto-N-triose I is a carbohydrate antigen that is used as an acceptor in the synthesis of trisaccharides. Lacto-N-triose I has been shown to have acidic hydrolysis and gel permeation chromatography. It can be used for the synthesis of oligosaccharides, which are important for glycosylation reactions. Lacto-N-triose I also has a glycosylation reaction that can be activated by desulfurization.

Sialyllacto-N-fucopentaose I is a high purity, custom synthesis, fluorinated carbohydrate that has been modified by methylation and click chemistry. This oligosaccharide is composed of a saccharide with a molecular weight of 908.5 g/mol and an enantiomeric purity of 99%. Sialyllacto-N-fucopentaose I is an Oligosaccharide with a CAS number of 61497-04-8. It is used in the synthesis of polysaccharides or as a monosaccharide or sugar substitute to produce high purity products.

GD1b oligosaccharide (shown as ammonium salt) is the carbohydrate moiety in one of the major gangliosides in neuronal and glial membranes; it has a core tetrasaccharide structure (Galβ1,3GalNAcβ1,4Galβ1,4Glc) with its two sialic acids linked α2,3/α2,8 to the inner galactose residue (Ledeen, 2009). GD1b ganglioside acts as a receptor for BK virus as well as for heat-labile LTII-a toxin, produced by enteropathogenic E. coli. GD1b ganglioside also interacts with tetanus neurotoxin (TeNT) and is crucial for its entry into cells (Kolter, 2012). The functional significance of ammonia in the brain is not yet fully understood. However, NH4 + stimulates Na+, K+ activated ATPase causing stabilization of the neuronal membranes of which gangliosides are major structural components. Further, ammonia is known to inhibit lysosomal enzymes which include enzymes degrading gangliosides (Modi, 1994).

Difucosyl (1-2,1-2)-iso-lacto-N-octaose (DFiLNO (1-2,1-2)) is an oligosaccharide that is found in human milk

6'-Sialyllactose-sp-biotin is a custom synthesis of a 6'-sialyllactose with a biotin moiety attached to the reducing end. The modification was done through fluorination, methylation, and monosaccharide synthesis. This product has CAS No. 1384441-62-6 and is an oligosaccharide saccharide that is polysaccharide containing glycosylated sugar. It is also a complex carbohydrate that contains many sugars in one molecule.

Tetrasaccharide; tumor-associated antigen; prognostic factor

2-Hydroxypropyl-b-cyclodextrin is a water-soluble drug that is chemically stable in aqueous media. It has been shown to be safe for use in the eye, with no significant side effects. 2-Hydroxypropyl-b-cyclodextrin has been shown to have anti-inflammatory properties and will not cause hemolytic activity. 2-Hydroxypropyl-b-cyclodextrin binds to retinoic acid receptors, which are found on cells of the corneal surface and in human spermatozoa. The binding of retinoic acid inhibits the production of enzymes that break down retinoids and prevents cell proliferation. This agent also interacts with other cellular components such as proteins, lipids, carbohydrates, nucleic acids, and hormones.

Asialylated glycosphingolipid and precursor for ganglioside biosynthesis. The compound is a major glycosphingolipid in human neutrophils and is involved in the regulation of superoxides as well as nitric oxide. Moreover, lactosylceramide accumulates in atherosclerotic plaques and is also found elevated in familial hypercholesterolemia and polycystic kidney disease. Animal studies revealed that lactosylceramide induces hypertrophy in cardiomyocytes via signal transduction pathway that is oxygen-sensitive.

GD1b ganglioside (shown as ammonium salt) is one of the major gangliosides in neuronal and glial membranes. It has a core tetrasaccharide structure (Galβ1,3GalNAcβ1,4Galβ1,4Glc) with its two sialic acids linked α2,3/α2,8 to the inner galactose residue, and ceramide linked β to position 1 on the reducing terminal glucose residue (Ledeen, 2009). GD1b ganglioside acts as a receptor for BK virus, as well as for heat-labile LTII-a toxin, produced by enteropathogenic E. coli. GD1b ganglioside also interacts with tetanus neurotoxin (TeNT) and is crucial for its entry into cells (Kolter, 2012). The functional significance of ammonia in the brain is not yet fully understood: see (Modi 1994).

Tri-guluronic acid sodium salt (1,4-linked α-L-sodium guluronotriose) is one of a number of oligosaccharides obtained from alginate which is a polysaccharide in brown seaweeds containing: blocks of repeating mannuronic acid sequences (M-M-M-M etc), repeating guluronic acid sequences (G-G-G-G etc), and alternating M-G-M-G sequences. This oligosaccharide can be released by acid hydrolysis (Shimokawa, 1996) and a number of biological activities have been discussed in a recent review (Xing, 2020).
