Loops, Turns & the Unsung Heroes (Module 2: The Weaver). Key concept: Connecting elements. Explain why loops and turns are functionally critical rather than filler between the real structure.

- Explain why loops and turns are functionally critical rather than filler between the real structure
- Distinguish tight turns, hairpin turns and flexible linkers
- Explain why glycine and proline dominate turn positions
