Question

5 suppose that there is an attraction between the blue and orange amino acids. stick the blue and orange amino acids together. lets also suppose that there is an attraction between the red and green amino acids. lets further suppose that there is a repulsion between the purple and yellow amino acids. make your amino acid chain assume the shape that seems to be the most logical.
a. what level of protein structure does the chain now represent?

Explanation:

The interactions between different amino - acids (attractions and repulsions) cause the amino - acid chain to fold into a specific three - dimensional shape. This folding based on interactions between non - adjacent amino acids represents the tertiary structure of a protein. The primary structure is just the linear sequence of amino acids, the secondary structure involves local folding patterns like alpha - helices and beta - sheets, and the quaternary structure involves the interaction of multiple polypeptide chains. Here, we are dealing with the folding of a single chain due to side - chain interactions.

Answer:

Tertiary structure
