Poly-glutamic acid (PGA) is a natural polymer composed of glutamate units with a unique set of properties. ：
1.Biodegradability: Polyglutamic acid is a biodegradable polymer that can be degraded to glutamate monomer by conditions such as microorganisms, enzymes, or acids and bases. This degradability gives polyglutamic acid potential in environmentally friendly and sustainable applications.
2.Biocompatibility: Polyglutamic acid has good biocompatibility and is not easy to trigger immune and toxic reactions. As a result, it is widely used in biomedical fields such as tissue engineering, drug delivery, and medical materials.
3.Water solubility: Polyglutamic acidIt has good solubility in water, which can form a transparent solution. This water solubility makes polyglutamic acid easy to process and apply in solution and can be used to prepare a variety of shapesNanoparticles, fibers, and filmsWait.
4.High molecular weight and high viscosity: Polyglutamic acid has a high molecular weight and viscosity, enabling the formation of high molecular weight polymer chains. This high molecular weight and high viscosity give polyglutamic acid rheological properties in both liquid and gel states, allowing it to be used in applications such as thickeners, colloidal stabilizers, and gel materials.
5.Good water retention: Polyglutamic acid has good moisture absorption and water retention properties, which can absorb and retain a large amount of water. This water retention allows polyglutamic acid to be used as a soil conditioner and humectant in the agricultural sector, helping to improve soil quality and plant growth.
6.Biological activity: Polyglutamic acid has a variety of biological activities, such as antioxidant, antibacterial, antitumor and immunomodulatory. These biological activities make polyglutamic acid have potential for applications in food, pharmaceuticals and cosmetics.
In summary, polyglutamic acid has the characteristics of biodegradability, biocompatibility, water solubility, high molecular weight and high viscosity, good water retention, and a variety of biological activities. These properties make polyglutamic acid have a wide range of applications in the fields of biomedicine, agriculture, food and cosmetics.
