Fucoidan: Marine Polysaccharide for Bioactivity-Oriented Research

1. Molecular Identity

• Chemical Name: Sulfated polysaccharide (structure varies by algal species and extraction method)
• CAS Number: 9072-19-9
• Source: Extracted from brown algae such as Fucus vesiculosus, Undaria pinnatifida, and others

2. Biochemical Relevance

Fucoidan is a structurally diverse class of fucose-rich sulfated polysaccharides naturally present in the cell walls of brown seaweeds. It is of growing interest in marine biotechnology, glycomics, and nutraceutical research due to its biological activity and biocompatibility.

3. Functional Properties

• Immune Support: Investigated for modulation of immune responses
• Anti-inflammatory Activity: Studied in relation to key inflammatory mediators
• Biological Compatibility: Non-toxic profile in in vitro models
• Antioxidant Capacity: Demonstrates radical scavenging properties

4. Research Applications

• Immunology and inflammation pathway studies
• Marine-derived polysaccharide structure–activity research
• Formulation of functional nutrition prototypes
• Evaluation in cellular models related to oxidative stress

5. Current Scientific Focus

Recent studies focus on Fucoidan’s role in:

• Modulation of cell signaling pathways
• Gastrointestinal and microbiome-related systems
• Hematological and endothelial system interactions
• Structure-dependent bioactivity variations by species and extraction method

6. Experimental Considerations

• Standardization of molecular weight and sulfation degree
• Evaluation of solubility and stability in aqueous systems
• Optimization for inclusion in complex research matrices

7. Regulatory Context

Fucoidan (CAS 9072-19-9) is classified as Generally Recognized As Safe (GRAS) in certain dietary supplement applications. For use beyond food or research, region-specific compliance and safety documentation may be required.

8. Research Outlook

Ongoing exploration includes:

• Structure–function correlations across marine species
• In vitro and ex vivo model development for polysaccharide analysis
• Fucoidan-based biomaterials for biotechnological applications
