Sialyllacto-N-tetraose a
Sialyllacto-N-tetraose a is a sialyl oligosaccharide found in human breast milk/colostrum which has biological significance with respect to anti-adhesion of pathogenic organism, providing precursors for biosynthesis of the brain and so on. It was found that the concentration level of Sialyllacto-N-teraose a in human colostrum is higher on day 3 than on day 1 collected from the start of lactation.

Sialyllacto-N-neotetraose c
Sialyllacto-N-neotetraose c is an oligosaccharide found in human breast milk. Two additional sialylated pentasaccharides include sialyllacto-N-tetraose-a and -b. Oligosaccharides containing N-acetyl (or N-glycolyl) neuraminic acid, i.e. sialylated oligosaccharides, are important components of glycoproteins and glycolipids. In nature, sialylated oligosaccharides often occur as homologous series, with incremental differences in composition, and as structural isomers with subtle differences in monosaccharide sequence and glycosyl linkage and, possibly, with presence or absence of molecular branching. A large number of such sialylated oligosaccharides occur in human milk, where they may have important biological functions. Major structural isomers of these acidic oligosaccharides in human milk are 3- and 6-sialyllactoses and the sialyllacto-N-tetraoses; appreciable amounts of 3- and 6-sialyllactosamines are found in human urine. (PMID:11471815). Oligosaccharides in human milk inhibit enteric pathogens in vitro and in vivo. Neutral milk oligosaccharides vary among individuals and over the course of lactation. (PMID:10683228).

Sialyllacto-N-tetraose b
Sialyllacto-N-tetraose b is a sialylated oligosaccharide normally occurring in human breast milk. Sialylated oligosaccharides are important components of glycoproteins and glycolipids and also occur as free oligosaccharides in several body fluids. In human milk, both free and bound sialylated oligosaccharides have potential biological activity and are known to inhibit viral infection. The acidic oligosaccharides of human milk are predominantly sialyloligosaccharides. Pathogens that bind sialic acid-containing glycans on their host mucosal surfaces may be inhibited by human milk sialyloligosaccharides. Sialyl oligosaccharides of human milk/colostrum are generally believed to be of biological significance, for example providing precursors for biosynthesis of brain. The levels of sialyllacto-N-tetraose are higher on day 3 than on day 1. These results are consistent with the view that during the first 3 d of lactation, the concentration of sialyl oligosaccharides in human colostrum change in accordance with the physiological demands of newborn infants.
