Question

fill in the blank question a chain of amino acids with a specific three - dimensional shape is called a(n) blank.

Explanation:

In biology (a subfield of Natural Science), a chain of amino acids that folds into a specific three - dimensional shape is known as a protein. Amino acids are linked together by peptide bonds to form a polypeptide chain, and when this chain folds into a specific 3D structure (due to interactions like hydrogen bonding, disulfide bridges, etc.), it becomes a protein, which has a specific function based on its shape.

Answer:

protein
