A) Secondary

B) Tertiary

C) Super-secondary

D) Domain

I) Final three-dimensional packaging of all three regions of a single polypeptide chain

II) Packing together of two or more adjacent folded sections within a contiguous piece of polypeptidechain (found to occur in many unrelated proteins)

III) Regular three dimensional folding pattern (repeating pi, psi values) of a contiguous segment of polypeptide chain

IV) Binding together and arrangement of separately folded polypeptide chains (subunits)

VI) Globular cluster of noncontiguous segments of polypeptide chain to form a unique, identifiable region of protein

II) Packing together of two or more adjacent folded sections ...

Solution Summary

The solution matches different proteins to their structure (secondary, tertiary, etc.) and clearly and concisely explains why these matches are made. Also, there is attached a written explanation of what in a protein determines its structure that is augmented with illustrative diagrams.
