(N-acetylneuraminosyl(a2-6)lactosamine)
(N-acetylneuraminosyl(alpha2-6)lactosamine) is widely distributed among tissues and is involved in biological processes such as the regulation of the immune response and the progression of colon cancer. Sialylation represents one of the most frequently occurring terminations of the oligosaccharide chains of glycoproteins and glycolipids. Sialic acid is commonly found alpha,6-linked to N-acetylgalactosamine (GalNAc). The biosynthesis of the linkage is mediated by a member of the sialyltransferase family, the beta-galactoside alpha,6-sialyltransferase (EC 2.4.99.1, ST6Gal.I). Although expressed by a single gene, this enzyme shows a complex pattern of regulation which allows its tissue- and stage-specific modulation. (PMID 11425186)
.6-Sialyllactosamine is an oligosaccharide found in human milk. Oligosaccharides in human milk inhibit enteric pathogens in vitro and in vivo. (PMID:10683228)

3-Sialyl-N-acetyllactosamine
3-Sialyl-N-acetyllactosamine is a normal sialyloligosaccharide that is present in human biofluids, and is one of the predominant oligosaccharides in human urine as a free form. The presence of these compounds in the urine is linked to the biosynthesis and degradation of the body glycoproteins, glycolipids, and glycans. Under certain pathological conditions, the total urinary carbohydrate-material is increased dramatically, and the number and ratios of the components present are also increased. Many of these pathological disorders are the result of a deficiency in a specific exoglycosidase. 3-Sialyl-N-acetyllactosamine have a sialyl(a2-3) linkage and is of interest in view of the discovery of uropathogenic Escherichia coli strains with binding specificity for sialyl(a2-3)galactosides.

6-Sialyl-N-acetyllactosamine
6-Sialyl-N-acetyllactosamine is an oligosaccharide widely distributed among tissues and is involved in biological processes such as the regulation of the immune response and the progression of colon cancer. Sialylation represents one of the most frequently occurring terminations of the oligosaccharide chains of glycoproteins and glycolipids. Sialic acid is commonly found alpha,3- or alpha,6-linked to galactose (Gal), alpha,6-linked to N-acetylgalactosamine (GalNAc) or alpha,8-linked to another sialic acid. The biosynthesis of the various linkages is mediated by the different members of the sialyltransferase family. The b-galactoside a2,6 sialyltransferase (EC 2.4.99.1, ST6Gal.I) is the only sialyltransferase so far identified able to catalyze the a2,6-sialylation of lactosamine. Although expressed by a single gene, this enzyme shows a complex pattern of regulation which allows its tissue- and stage-specific modulation. The level of expression of the sialyl-alpha2,6-lactosaminyl structures and of ST6Gal.I show a strong dependence on neoplastic transformation and differentiation in several tissues.
