What is Prussic Acid?

Alginic acid is a natural polysaccharide. Its chemical composition is a linear copolymer of Lu-D-mannuronic acid (M) and a-L-guluronic acid (G) through 1, 4 bonding, G The content of M and M in alginic acid has a significant effect on the gelation properties of fibers. Alginic acid exists in the cytoplasm in its natural state and plays a role in strengthening the cell wall. Alginic acid combines with various cations in seawater to form various alginates. The extract obtained from seaweed is usually sodium alginate. Sodium alginate has the characteristics of thickening, suspending, emulsifying, stabilizing, forming gel, forming film and spinning fiber. It has a long and wide application in food, paper making and cosmetic industries, especially in the field of biomedical engineering in recent years. Found important uses. ^[1]

[Function and use]

Common

Alginic acid industry

Alginic acid can quickly absorb water and can be used as a dehydrating agent and sizing agent in the paper and textile industry. Its main function is to use it as an emulsifier or thickener in the food industry and daily chemical industry in the form of sodium alginate or potassium alginate. It is a common ingredient in foods and cosmetics such as ice cream and milkshakes.

Alginic acid medicine

In the pharmaceutical industry, alginic acid is a commonly used excipient: its viscosity makes it a binder for tablets; it swells with water and is used as a disintegrant to disperse tablets in the human body; or as The dispersant disperses the active ingredient into the liquid to become a suspension; alginate is used as a slow-release drug. It is used in dentistry to replace plaster and rubber to make dental molds. Alginic acid itself can be used as an absorbent to treat heavy metal poisoning ^[3] .
