2.1 The Alpha Helix

The Alpha Helix (Module 2: The Weaver). Key concept: i→i+4 hydrogen bonding. Explain the i → i+4 hydrogen bond that holds a helix together, from C=O of residue i to N–H of residue i+4.

• Explain the i → i+4 hydrogen bond that holds a helix together, from C=O of residue i to N–H of residue i+4
• Recall that one helical turn spans roughly 3.6 residues
• Place helix hydrogen bonds correctly along a sequence
