The collagen molecule is too big to penetrate the outer layers of the skin unless it is injected.

Their contribution helped to elucidate the three-chain structure of the collagen molecule.

This clipping step is necessary for collagen molecules to function normally and assemble into fibrils outside cells.

You can't get the collagen molecule into your skin.

The fibrils are made up of collagen molecules 200 times as long as they are wide.

In the presence of specific collagen molecules, the calcium and phosphorous ions crystallize.

All collagen molecules are made of three protein strands (called alpha chains).

Instead of forming collagen molecules, the abnormal protein builds up in cartilage cells (chondrocytes).

The human collagen molecule is a chain of 1,000 amino acids.

As a graduate student, he and Ramachandran worked on the triple helix structure of the collagen molecule.
