Chitosan (chitosan), also known as chitin, is obtained by deacetylation of chitin, which is widely present in nature, and its chemical name is polyglucosamine (1-4)-2-amino-BD glucose .
Chemical nature
Under certain conditions, chitosan can undergo chemical reactions such as hydrolysis, alkylation, acylation, carboxymethylation, sulfonation, nitration, halogenation, oxidation, reduction, condensation, and complexation, and can generate a variety of different chemical reactions. Performance of chitosan derivatives, thereby expanding the application range of chitosan.
Performance
Because chitosan has free amino groups in its molecule, it is easy to form a salt in an acidic solution and has a cationic nature. As the number of amino groups in the chitosan molecule increases, its amino characteristics become more pronounced. This is where its unique properties lie, which lays the foundation for many of the biological and processing characteristics of chitosan.
Physiological activity
1. Control cholesterol　
Chitosan is a natural material with strong anion adsorption capacity and is suitable for lowering cholesterol without any side effects.
2. Inhibit bacterial activity　
Chitosan is easy to dissolve in weak acid solvents. It is particularly worth pointing out that the dissolved solution contains amino groups (NH2+), which inhibit bacteria by binding negative electrons. Chitosan's antibacterial activity makes it widely used in medicine, textiles, food and other fields.
3. Prevent and control hypertension　
One of the most influential factors for high blood pressure is chloride ion (cl-). It is usually ingested through salt. Chitosan excretes chloride ions through the adsorption between its own chloride ions and ammonia ions. Therefore, chitosan reduces angiotensin II. It helps prevent high blood pressure, especially those who consume excessive amounts of salt.
4. Adsorption and excretion of heavy metals　
A notable characteristic of chitosan is its adsorption capacity. Many low molecular weight materials, such as metal ions, cholesterol, triglycerides, cholic acid and organic mercury, can be adsorbed by chitosan.
5. Immune effect
Chitosan has higher protein adsorption capacity; under the action of degrading enzymes (lysozyme, kitinase), chitosan is degradable; chitosan has higher biodegradability; chitosan has It selectively inhibits the growth of oral streptococcus without affecting the growth of other beneficial bacteria.
Application
1. Chitosan for cosmetics
Chitosan for cosmetics has good moisture absorption, moisturizing, conditioning, antibacterial and other functions; it is suitable for moisturizers, shower gels, facial cleansers, mousses, high-end creams, lotions, colloidal cosmetics, etc.
2. Chitosan special for flocculant
Chitosan and its derivatives have good flocculation and clarification effects, and use the adsorption properties of chitosan to have good effects in water purification.
3. Special chitosan for agriculture, feed and bait
Chitosan is a natural plant nutrient growth promoter-the raw material of foliar fertilizer. The foliar fertilizer compounded with chitosan can not only kill insects, resist disease, and play a role in fertilizer, but also Decompose animal and plant residues and trace metal elements in the soil, thereby converting them into plant nutrients, enhancing plant immunity, and promoting plant health;
