Lacto-N-fucopentose II - the golden key to unlocking the secrets of nutrition and health in early life

Lacto-N-fucopentose II is one of the core members of human breast milk oligosaccharides and is known as "the original prebiotic of life". It is not only an important component of bioactive ingredients in breast milk, but also an indispensable high-end functional raw material in the fields of modern nutritional science, infant formula foods and functional foods.

Chemical Information

Chemical name: Lacto-N-fucopentose II

Common name: LNFP II

Chemical formula: C32H55NO25

Molecular weight: 853.77 g/mol

CAS number: 21973-23-9

Structural features

Lacto-N-fucopentose II is a complex oligosaccharide with an exquisite structure that is unique in that:

Precise core structure: With lactose as the core, N-acetylglucosamine, galactose and fucose are connected in sequence, forming an extension of the unique LNT (lacto-N-neotetraose) core skeleton.

Key α-1,4 fucosylation: Its terminal fucose is connected to N-acetylglucosamine in the core structure through an α-1,4 glycosidic bond. This specific connection method is a decisive factor in its biological activity, allowing it to be exploited by specific microorganisms and precisely bind to lectin receptors on the surface of host cells.

Main applications and advantages

The gold standard of high-end infant formula

Simulated breast milk function: Breast milk oligosaccharides are the third largest solid component in breast milk and are crucial to the healthy development of infants and young children. Adding LNFP II can make the formula closer to the composition and function of breast milk, providing vital nutritional support for babies who cannot achieve exclusive breastfeeding.

Targeted regulation of intestinal flora: LNFP II can be used as an exclusive nutrient and is preferentially utilized by beneficial bacteria (such as bifidobacteria) in the infant's intestines, thereby promoting the proliferation of beneficial bacteria, inhibiting the colonization of harmful bacteria, and building a healthy intestinal microecological environment.

The star ingredient of the new generation of functional foods and health products

Enhance immune regulation: LNFP II can regulate the immune response by interacting with specific receptors on the surface of intestinal immune cells, helping to balance the immune system and providing new solutions for enhancing self-resistance.

Promote intestinal barrier health: By promoting the growth of beneficial bacteria and their metabolites, LNFP II helps maintain and strengthen the intestinal mucosal barrier function, reduce intestinal permeability, and lay a solid foundation for systemic health.

Innovative tools for cutting-edge biomedical research and drug development

Microbial interaction studies: LNFP II is an ideal molecular tool for studying the interactions of specific pathogens with host cells. Many pathogenic bacteria colonize by recognizing oligosaccharide structures on the intestinal mucosa, and LNFP II can serve as a "bait" molecule to block this process.

Immunology research and biomarkers: Its precise role in immune regulation makes it a new target for studying autoimmune diseases, allergies, etc., and is expected to become a diagnostic or prognostic biomarker for related diseases.

Conclusion

Lacto-N-fucopentose II is more than just a sugar molecule, it is the bridge between early life nutrition and lifelong health. From creating more advanced infant formula, to developing innovative functional products that regulate immunity and improve intestinal health, to deciphering the complex dialogue between hosts and microorganisms, its application prospects are broad.
