Globular Proteins

Globular Proteins

 

crystalline proteins that are easily soluble in water or weak saline solutions; their molecules are close to spherical (the ratio of the sphere’s axes does not exceed 5). Such a molecular structure is determined by the spiralization of the peptide chain and by its dense packing, which is due to the tertiary structure. Many globular proteins exhibit enzymatic activity. Globulins, myoglobin, and ribonuclease are among the important globular proteins. Some proteins, such as actin, exist in both globular and elongated fibrillar form.
