Alginate Oligosaccharide

Alginate Oligosaccharide

Alginate oligosaccharide is yellow brown powder, and water-soluble with good stability. whose degree of polymerization is lower than 20,  was produced by the degradation of algin, using different methods(acid degradation, enzymatic degradation, and oxidation degradation). 

Alginate oligosaccharide is a linear polysaccharide consisting of α-L-guluronate (G) and β-D-mannuronate (M). According to the arrangement of these residues, three products, which are homopolymer (polyguluronate, PG ), ( polymannuronate, PM) and heteropolymer (a mixed sequence of these residues, PMG) are supplied.

Alginate oligosaccharide has many biological functions, and can be applied extensively in medical industry, foods, daily chemical industry, feedstuff and agriculture. 

Biological functions 

1. Anti-tumor activity 

Alginate oligosaccharide can activate nonspecific immune and specific immune system. After activation, macrophage cell can inhibit tumor cell proliferation and kill the tumor. 

2.  Anticoagulation 

Heparin, as an effective anticoagulant, gradually displayed its side effects in clinical. Alginate oligosaccharide has good anticoagulant activity and decreases side effects. 

3. Lowering blood lipids and glucose 

Appropriate doses of alginate oligosaccharide can prevent hypercholesterolemia well, has the function of lowering blood lipids and maintaining the normal cardiovascular function. 

4. The free radical scavenging activity and antioxidation 

Alginate oligosaccharide has the free radical scavenging activity, significantly reduces lipid peroxide content and improves peroxidase and SOD activity.

5. Anti-inflammatory  

Alginate oligosaccharide has abundant source, theoretically is a good anti-inflammatory substitute of sLex, sLea and heparin-derived oligosaccharide, and has good potential medical value. 

6. Immunoregulatory activity 

Alginate oligosaccharide can stimulate the differentiation, mature, breeding of immune cells (such as macrophages, T-lymphocytes, B-lymphocytes, etc), refreshes and strengthens the body's immune system, and carries out its biological function through immunoregulatory activity. 

7. Growth promotion 

In plant alginate oligosaccharide is also an important signal molecule, can promote the growth of plants, and can improve the resistance of to plant diseases and insect pests.

1. Medical industry 

Alginate oligosaccharide has a variety of biological function. According to its medical function, there will be more drugs derived from alginate oligosaccharide. 

• Cardiovascular drugs: Polysaccharide sulfate

• Antihyperlipidemic drugs: Propylene glycol mannurate sulfate

• Antiviral drugs: Poly-mannaguluronic acid 

• Antiurolithic drugs: Polyguluronate sulfate 

2. Food industry 

As food materials or food additives,alginate oligosaccharide  can be applied in food industry. Alginate oligosaccharide has the function of intestinal immune regulation, detoxification, lowering blood lipids and glucose , anticoagulation, anti-inflammation and Immune system regulation, and can be used as food of patients with obesity, diabetes, colorectal cancer, and habitual constipation. Alginate oligosaccharide can also be added to the spices, dairy products, and fruit juice, which can both enrich the taste of products, and improve the nutrition. 

• Removal of heavy metal ions: Huahai lead excreting milk powder

• Blood glucose-lowering activity: Jiangtangle 

3. Daily chemical industry 

With its biological function diversity, alginate oligosaccharides are widely used in daily chemical industry.

• Moisturizing products

• Sunscreen products 

• Hair care 

4. Feedstuff industry 

Alginate oligosaccharide overcomes deficiencies of previous antibiotics, probiotics and enzyme preparation. Alginate oligosaccharide is a good nature feed additive with low dosage, no residual and strong stability.  

• Feed additive in animal husbandry: pig, cattle, chicken, etc. 

• Feed additive in aquaculture: sea cucumber, abalone, shrimp, etc.

5. Agriculture 

Alginate oligosaccharide can activate plant immune system, improve the disease resistance, promote cell activation, and stimulate plant growth.
