collagenous triplet

Repeating unit of collagen fibers. Glycine is the invariant residue, being the only amino acid residue small enough to occupy the crowded interior of the collagen triple helix. Proline & hydroxyproline are frequently associated with evenly spaced glycines found 3 residues apart.

General
