What is the albumin structure?

Albumin is a globular protein characterized by its compact and soluble structure, primarily consisting of a single polypeptide chain. It features multiple alpha-helices and loops, forming a heart-shaped conformation that allows it to carry various molecules. The protein's structure includes several binding sites for ligands, enabling it to transport fatty acids, hormones, and drugs in the bloodstream. Its stability and flexibility are crucial for its physiological functions, including maintaining oncotic pressure and acting as a reservoir for nutrients.
