This collagen product contains polymers of the group of glycosaminoglycans bonded to the collagen substance at least in part by chemical bonds conveyed by polyvalent metal cations. The chemical bonds are conveyed by coordinately bonded metal compounds of the group of transition metals, mainly Cr, Zr, Al, Fe, Mn or Ti, and/or by the polyvalent cations of alkaline earth metals, mainly Ca, Mg, Zn, Ba or Sr. In addition, the invention relates to the method for the manufacture of the abovementioned collagen product and to the use thereof. |
