Which amino acid is essential for the central core of a collagen triple helix?
Which amino acid is essential for the central core of a collagen triple helix?
Glycine is the only amino acid small enough to fit within the tight space of the collagen triple helix's central core.
Which amino acids provide rigidity to collagen?
Which amino acids provide rigidity to collagen?
Proline and hydroxyproline contribute to the rigidity of the collagen triple helix due to their unique ring structure, which restricts rotation around their bonds.
Which amino acid helps stabilize collagen with H-bonds?
Which amino acid helps stabilize collagen with H-bonds?
