3′-Sialyllactose

Description:
3′-Sialyllactose is a complex carbohydrate, specifically a sialylated oligosaccharide, which consists of a lactose core with a sialic acid residue attached at the 3′ position of the galactose unit. This compound is notable for its role in biological processes, particularly in cell recognition and signaling, as well as its presence in human milk, where it contributes to the development of the infant's immune system and gut microbiota. The presence of the sialic acid moiety imparts unique properties, such as increased solubility and resistance to enzymatic degradation, which enhances its biological functionality. 3′-Sialyllactose is also studied for its potential prebiotic effects and its ability to modulate gut health. In terms of physical properties, it is typically a white to off-white powder, soluble in water, and may exhibit hygroscopic behavior. Its applications extend to food science, nutrition, and potential therapeutic uses, particularly in the context of infant nutrition and gut health.
