<p>a-D-Galactosyl-mannotriose is a complex oligosaccharide, which is derived from plant materials such as leguminous seeds. Its mode of action involves selectively promoting the growth of beneficial gut bacteria, particularly bifidobacteria and lactobacilli, through its structural composition that resists hydrolysis by human digestive enzymes. This non-digestibility allows it to reach the colon intact, where it can exert its prebiotic effects.</p>

<p>Neolactotetraosylceramide (NT4) is a glycoconjugate that is found in human serum. It has been shown to bind to the receptor site of monoclonal antibodies and inhibit the binding of tumor necrosis factor-α (TNF-α), which is involved in immune system regulation. NT4 has also been shown to block the activity of receptors on human neutrophils, which may be due to its structural similarity to lactotetraosylceramide. NT4 has been implicated as a potential cause for autoimmune diseases and cancer tissues, due to its structural similarity with glycoproteins that are found on cell surfaces. The optimum pH for NT4 is 7.5 and its glycan structure consists of two mannose residues linked by an alpha-1,6 linkage. This glycoconjugate binds well with blood group A and B antigens, but not with blood group O antigen. NT4 elicits antibody response</p>

<p>Xyloglucan is a heptasaccharide that is an important component of the plant cell wall. Xyloglucan heptasaccharides are found in the cell walls of many plants, including banana and potato. Xyloglucan heptasaccharides are composed of alternating glucose and xylose residues, with a glycosidic linkage between two xylose residues. This linkage can be hydrolyzed by α-amyrinase to yield two xylose monomers. The conformational properties of xyloglucan depend on its stereochemistry, which has been shown to affect its ability to inhibit inflammatory bowel disease (IBD). Xyloglucan heptasaccharides have also been shown to bind to bacterial cells, inhibiting their growth.</p>

<p>NA3F is a N-glycan that is found on various glycoproteins and glycolipids. It consists of sialic acid, galactose, and fucose sugars in the ratio 3:2:1. NA3F N-glycans are synthesized by the removal of the terminal sialic acid residue from an Asn-linked oligosaccharide precursor. These types of glycans are found on high mannose (HMan) and hybrid (HHyb) glycans. The synthesis of NA3F N-glycan requires the activity of two enzymes: peptidase and sialyltransferase. The enzyme peptidase cleaves an α(1,4)-linked oligosaccharide at the nonreducing end to form a free α(1,6) linked oligosaccharide with a terminal α(1,2) linked mannose residue. This process releases the terminal</p>

<p>Salacinol is a naturally occurring alpha-glucosidase inhibitor isolated from an Ayurvedic traditional medicine Salacia reticulata.</p>

<p>Galactostatin is an inhibitor of β-galactosidase.</p>

<p>Disialyllacto-N-hexaose I is a complex carbohydrate that belongs to a class of saccharides called polysaccharides. Disialyllacto-N-hexaose I is synthesized through the methylation and glycosylation of sucrose. It has been modified by Click chemistry with a maleimide group to create an amide bond between the terminal alpha position on the glucose residue and the terminal alpha position on the N-acetylglucosamine residue. This modification can be used for Polysaccharide analysis, such as MALDI TOF MS. Disialyllacto-N-hexaose I has a CAS number of 137636-98-7 and has been shown to have high purity without any impurities or contaminants.</p>
