globular protein

Globular proteins are a class of proteins characterized by their compact, roughly spherical shape. This three-dimensional structure is crucial for their function. Unlike fibrous proteins, which have elongated structures, globular proteins are typically soluble in water and have low viscosity.1

X-ray diffraction studies have been instrumental in understanding the conformation of globular proteins, revealing intricate folding patterns of their peptide chains. These proteins play vital roles in biological systems, acting as enzymes, antibodies, and transport molecules within blood plasma. Examples include albumins and globulins, which have diverse functions ranging from carrying substances to supporting immunity. Denaturation, a process that disrupts the protein's structure, can lead to a loss of its biological activity.2345
