Lacto-N-tetraose
Based on 1 publication(s) in Google Scholar
Lacto-N-tetraose is the significant core structure of human milk oligosaccharides (HMOs) naturally existing in human milk. Lacto-N-tetraose is consist of galactose, N-acetylglucosamine, and glucose moieties. Lacto-N-tetraose has prebiotic effect, immune regulatory effect, anti-inflammatory effects, intestinal cell responses regulatory effect, antibacterial activity and antiviral activity. Lacto-N-tetraose has been widely added to infant formula.

Biological Activity
HMOs exhibits antimicrobial and antibiofilm activity against Streptococcus agalactiae, antibiofilm activity against Methicillin-resistant Staphylococcus aureus (MRSA), and antimicrobial activity against both Acinetobacter baumannii and Clostridium difficile[2].
Lacto-N-tetraose (500-2000 μg/mL) does not cause clastogenic or aneugenic signs in human peripheral blood lymphocytes, nor increase the percentage of micronucleated cells[3].
