The unique triple helix structure of collagen is essential for its mechanical properties and biological functions. Recent research has focused on collagen mimetic peptides (CMPs), which are ...

Figure 1: Pauling and Corey's first guess at the structure of collagen, showing a beautifully drawn illustration of their proposed three-chain helix: it was wrong, and they later withdrew it.

Collagen is characterized by its distinctive triple-helix structure, which is comprised of long chains of amino acids, primarily glycine, proline, and hydroxyproline. This unique configuration gives ...
