Chitosan is a natural polysaccharide organic substance, obtained from the acylation reaction of glucose and coenzyme A. It is the main component of chitin and exists in the exoskeletons of crustaceans and fungi. Chitosan has many unique properties, such as good biocompatibility, strong biodegradability, and wide functionality. Therefore, it is widely used in fields such as food, medicine, and cosmetics.
The monomer molecular weight of chitosan refers to the average number of glucose units contained in chitosan molecules. The larger the monomer molecular weight, the more complex the molecular structure of chitosan, and its properties will also differ. The monomer molecular weight of chitosan is usually expressed by the weight – average monomer molecular weight (Mw). For chitosan, chitosan with an Mw of 1600 can be considered a type of chitosan with a relatively high molecular weight. This kind of chitosan has the following characteristics.
Firstly, chitosan has very good biocompatibility. Biocompatibility refers to the ability of chitosan to interact with living organisms. Because chitosan itself has a natural polysaccharide structure, its compatibility with living organisms is very high. Chitosan can bind to some specific receptors in cell membranes, thereby exerting different biological functions. For example, in tissue engineering, chitosan can be used as a scaffold material for repairing and regenerating tissues.

Secondly, chitosan has good biodegradability. Biodegradability refers to the ability of chitosan to be decomposed by enzymes in living organisms and gradually degraded. Chitosan can be decomposed by an enzyme called chitosanase, and finally converted into harmless substances such as water and carbon dioxide, which will not pollute the environment. This characteristic makes chitosan an ideal material for preparing biodegradable packaging materials, reducing the impact of plastic waste on the environment.
In addition, chitosan has wide functionality. It has extensive applications in fields such as food, medicine, and cosmetics. In the food industry, chitosan can be used as a food additive to enhance the stability and storage life of food. In the medical field, chitosan has multiple functions such as antibacterial, anti – inflammatory, and wound repair, and can be used for antibacterial dressings for wounds, delivery materials for sustained – release drugs, etc. In the cosmetics field, chitosan can be used as a moisturizer, antioxidant, etc., to enhance the stability and efficacy of cosmetics.
