Description

Sialyllacto-N-tetraose b, also known as LS-tetrasaccharide b or LSTB, belongs to the class of organic compounds known as n-acylneuraminic acids. These are neuraminic acids carrying an N-acyl substituent. Sialylated oligosaccharides are important components of glycoproteins and glycolipids and also occur as free oligosaccharides in several body fluids. The levels of sialyllacto-N-tetraose are higher on day 3 than on day 1. Sialyllacto-N-tetraose b is an extremely weak basic (essentially neutral) compound (based on its pKa). Sialyl oligosaccharides of human milk/colostrum are generally believed to be of biological significance, for example providing precursors for biosynthesis of brain. 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. 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. Sialyllacto-N-tetraose b is a sialylated oligosaccharide normally occurring in human breast milk. Pathogens that bind sialic acid-containing glycans on their host mucosal surfaces may be inhibited by human milk sialyloligosaccharides.
