Collagen Product InformationCollagen is an inert, rigid protein found predominantly in skin, ligaments, bones and teeth. Its most distinctive characteristic in its role as a transmitter of mechanical force is its inelasticity. The fundamental structural unit is a tropo-collagen, a molecular rod about 2600 Å in length and 15 Å in diameter with a molecular weight of 300 kDa. In tendons, these macromolecules, grouped as collagen fibrils, run parallel to the axis; in skin the fibrils are interlaced and branched. Collagen fibers with limited cross-linkages (i.e., unaged) will dissolve to some extent in dilute acid or concentrated neutral salt solutions. Related Products: Collagenase (CLS1-4/CLSPA)
