Identification
Common NameSialyllacto-N-tetraose a
ClassSmall Molecule
DescriptionSialyllacto-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. (PMID:17587674)
