Description:
Collagen is an inextensible fibrous protein that is found in connective tissue - bone, tendons, and skin. The objective of this exercise is to develop an understanding of the fibrous portion of collagen and to show how the different levels of protein structure come together and form a highly ordered and stable fiber. Three helicial peptides combine to form tropocollagen, and five tropocollagens combine to form a fiber segment. It is important to realize that in an actual fiber segment the ends of the tropocollagen would be staggered rather then flush-cut as shown in the model presented herein. The staggered ends would permit overlap in the association of the tropocollagens in adjacent segments, and thus aid in forming a strong fiber.
