Technical Abstract: Animal hides, a major byproduct of the meat industry, are a rich source of collagen, a structural protein of the extracellular matrix that gives strength and form to the skin, tendons and bones of mammals. The structure of fibrous collagen, a long triple helix that self-associates in a staggered array to form a matrix of fibrils, fibers and fiber bundles, makes it uniquely suitable as a scaffold for biomaterial engineering. A major challenge for medical materials is the stabilization of the collagen structure by means that are acceptable for the proposed end use. Our bovine type I collagen microfibril model comprises five right-handed triple helices in a left-handed super coil containing gap and overlap regions as well as the nonhelical telopeptides. This model can serve as a tool for predicting or visualizing the results of reactions intended to stabilize the matrix, insert an active agent, or otherwise modify collagen.
