IB Biology: B1.2-Primary Structure of Proteins

Front

What does the primary structure of a protein refer to?

Back

The specific sequence of amino acids that are joined together to form a polypeptide chain.

Front

How does the unique sequence of amino acids affect a protein?

Back

It determines how the polypeptide chain will fold, ultimately leading to the three-dimensional structure of the protein.

Front

Why is the precise position of each amino acid within the protein structure critical?

Back

Because it determines the protein's shape, and a change in the sequence may result in significant changes to the protein’s structure and function.
