BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The ensemble of formations and folds in a single linear chain of amino acids-sometimes called a polypeptide-constitutes the tertiary structure of a protein. Finally, the quaternary structure of a protein refers to those macromolecules with multiple polypeptide chains or subunits.

Detailed explanation-2: -2 Tertiary and Quaternary Structures. Tertiary structure refers to the configuration of a protein subunit in three-dimensional space, while quaternary structure refers to the relationships of the four subunits of hemoglobin to each other.

Detailed explanation-3: -Quaternary structure However, some proteins are made up of multiple polypeptide chains, also known as subunits. When these subunits come together, they give the protein its quaternary structure.

Detailed explanation-4: -Quaternary structure exists in proteins consisting of two or more identical or different polypeptide chains (subunits). These proteins are called oligomers because they have two or more subunits.

Detailed explanation-5: -Quaternary structure refers only to proteins that are composed of multiple polypeptides. These separate polypeptides are held together by the same intermolecular forces found in secondary and tertiary structures.
