Chitosan Oligosaccharide (COS), also known as chitooligosaccharide or chitosan oligosaccharides, is a low molecular weight product derived from the degradation of chitosan, which is the deacetylated product of chitin.
Chitosan Oligosaccharide (COS)
Chitosan Oligosaccharide (COS) is an oligomeric derivative of chitosan, which is composed of β-(1→4) glycosidic linkages of D-glucosamine units. It is a water-soluble, highly bioactive, and low molecular weight product with excellent functional properties. The polymerization degree of COS typically ranges from 2 to 10, making it a valuable compound in various applications.
Properties and Characteristics
Water Solubility: COS exhibits excellent water solubility, which allows it to be easily absorbed and utilized by the human body, with an absorption rate as high as 98%.
Biological Activity: Being a cationic polysaccharide, COS possesses numerous biological activities, including immune modulation, pH regulation, and hormonal balance. It is also known to lower blood lipids, blood sugar, and blood pressure.
Antioxidant and Anti-inflammatory: COS exhibits potent antioxidant and anti-inflammatory properties, which help to protect cells from oxidative stress and reduce inflammation.
Safety and Stability: COS is generally considered safe for consumption and is stable under normal conditions, avoiding contact with strong oxidizing agents.
Applications
Healthcare: Due to its ability to modulate immune function, COS is widely used in healthcare products, such as dietary supplements and functional foods. It is also studied for its potential in treating metabolic diseases and cancer.
Cosmetics: The antioxidant and anti-aging properties of COS make it a valuable ingredient in cosmetic products, helping to improve skin health and delay skin aging.
Agriculture: COS has been shown to promote plant growth and enhance crop resistance to stress factors, making it a potential biofertilizer and biostimulant in agriculture.
Environmental Protection: Its cationic nature allows COS to bind and remove heavy metals and other pollutants from water and soil, making it an eco-friendly material for environmental remediation.
