Detailed explanation-1: -Some globular proteins have a quaternary structure, and it is formed when two or more globular protein molecules (monomer) join together and form a multimeric unit. Hemoglobin is a good example of a protein that has a quarternary structure.

Detailed explanation-2: -The globular shape of a protein is called the tertiary structure. This structure results when the chains of polypeptides coil around to give a spherical shape. These are usually soluble in water. Insulin and albumins are common examples of globular proteins.

Detailed explanation-3: -Globular structure and solubility The molecule’s apolar (hydrophobic) amino acids are bounded towards the molecule’s interior whereas polar (hydrophilic) amino acids are bound outwards, allowing dipole-dipole interactions with the solvent, which explains the molecule’s solubility.

Detailed explanation-4: -One of the most common protein shapes is spherical ("globe-like") proteins, also known as globular proteins or spheroproteins. Globular proteins, unlike fibrous or membrane proteins, are generally water-soluble (forming colloids in water).
