Metabolite Identification
Common Name3-Sialyl-N-acetyllactosamine
Description3-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.
