Three lumpy polypeptide chains wind tightly around each other in this collagen triple helix model. Collagen is the protein fiber that gives skin, bone and tendon their strength. The strands are sculpted with a beaded, knobbly surface that suggests packed atoms, twisting in a steady spiral from base to tip. The tall, slender column has an organic, almost carved look. A neat teaching piece for biochemistry and anatomy classrooms, and an unusual science display for a desk or shelf.
