The 5 pages that link to Proline, each with the reason it gives.

• Peptide bondRelated: Its ring makes the adjacent peptide bond more likely to adopt the cis configuration.

• Alpha helixRelated: Its geometry and missing backbone hydrogen often disrupt alpha helices.

• OrnithineRelated: Ornithine can be converted toward proline through pyrroline-5-carboxylate.
