Calcium alginate

Description:
Calcium alginate is a biopolymer derived from alginic acid, which is extracted from brown seaweed. It is a white to yellowish powder that is soluble in water, forming a viscous gel upon hydration. The chemical structure consists of linear chains of (1→4)-linked β-D-mannuronic acid and α-L-guluronic acid residues, which are cross-linked by calcium ions, giving it its gel-forming properties. Calcium alginate is widely used in food, pharmaceuticals, and biotechnology due to its biocompatibility and non-toxicity. In the food industry, it serves as a thickening agent, stabilizer, and emulsifier. In medicine, it is utilized for wound dressings and drug delivery systems, as it can encapsulate active ingredients and release them in a controlled manner. Additionally, calcium alginate is biodegradable, making it an environmentally friendly option compared to synthetic polymers. Its ability to form gels under specific conditions allows for various applications, including encapsulation and controlled release, making it a versatile material in both industrial and research settings.
