Sequence of amino acids is important in:
Correct answer: A. Primary structure
- A. Primary structure
- B. Tertiary structure
- C. Secondary structure
- D. Quaternary structure
Explanation
The sequence of amino acids in a polypeptide chain, known as the primary structure, is crucially important for determining a protein's overall function and properties. The sequence dictates how the amino acids are arranged, and this specific order influences how the protein folds into its unique three-dimensional structure. The primary structure is the foundation upon which the higher-order structures of the protein, such as the secondary, tertiary, and quaternary structures, are built.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
