Description

3-Fucosyllactose is a structurally important human milk oligosaccharide (HMO) with the CAS registry number 41312-47-4. This compound is a key functional ingredient valued for its prebiotic activity and role in supporting infant gut health and immune system development. It is primarily utilized by manufacturers in the infant formula, nutritional supplements, and functional food industries seeking to enhance product profiles with bioactive components.

Application

• Infant Formula Fortification: As a major HMO, it is added to formula to more closely mimic the composition and functional benefits of human breast milk.
• Prebiotic Supplements: Serves as a selective substrate to promote the growth of beneficial gut microbiota such as Bifidobacteria.
• Clinical & Medical Nutrition: Incorporated into specialized nutritional products for supporting gut health and immune function in vulnerable populations.
• Functional Food & Beverages: Used in the development of gut-health-promoting consumer products like yogurts, drinks, and snacks.
• Pharmaceutical Intermediates: Acts as a chiral building block or reference standard in glycobiology research and drug discovery.
• Microbiome Research: Employed as a critical reagent in scientific studies investigating host-microbe interactions and prebiotic mechanisms.
