Question

In the tertiary structure of proteins, what come together?

• A. Amino acids subunits
• B. Peptide bonds
• C. Side chains of amino acids
• D. Different polypeptide subunits

Answer 1

The correct option is C Side chains of amino acids

The primary structure of a protein is its amino acids linked in a polypeptide. In secondary structure, hydrogen bonds are formed between the atoms involved in the peptide bonds. In tertiary structure, the secondary structure further folds so that the side chains of the different constituent amino acids of the protein come together. It is at this level that most proteins are ready for there function.
