If the R groups in an alpha helix were to point inward rather than outward, what would be the likely consequence?

• A. Formation of additional hydrogen bonds, increasing stability.
• B. Increased steric hindrance leading to decreased stability of the helix.
• C. Decreased steric hindrance leading to increased stability of the helix.
• D. No change in stability as R group orientation does not affect the helix.

Answer: (B)
