Detailed explanation-1: -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-2: -The quaternary structure of a protein is the association of several protein chains or subunits into a closely packed arrangement. Each of the subunits has its own primary, secondary, and tertiary structure. The subunits are held together by hydrogen bonds and van der Waals forces between nonpolar side chains.

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.
