Which of the three different representations of protein structure is most useful for studying the interior shapes formed by the folds of the protein?
three models of a protein structure.
the first (from left to right) structure is a space-filling model. here, each atom is represented by a ball of specific color.
the second structure is a ribbon model. here, the sequence looks like a ribbon twisted or coiled to match the shape of the protein.
the third structure is a backbone model. here, the sequence is represented as a thread.
