CAS 64003-54-9: Sialyllacto-N-tetraose b

Description: Sialyllacto-N-tetraose b (CAS number 64003-54-9) is a complex carbohydrate, specifically a glycan, that is part of the family of oligosaccharides. It is composed of a core structure derived from lactose, with additional sialic acid residues that contribute to its unique properties. This compound is characterized by its role in biological processes, particularly in cell recognition and signaling, as well as its involvement in immune responses. Sialyllacto-N-tetraose b is often found in human milk and is thought to play a crucial role in the development of the infant gut microbiome and immune system. Its structure includes multiple sugar units, including N-acetylglucosamine and galactose, linked together in a specific arrangement that influences its biological activity. The presence of sialic acid enhances its negative charge, which can affect interactions with proteins and other biomolecules. Overall, Sialyllacto-N-tetraose b is significant in both nutritional and biomedical research due to its potential health benefits and functional properties.
