Kinetic characterization of the deproteinization of trabecular and cortical bovine femur bones.

摘要: The present study proposes an interpretation of the mechanism bone deproteinization. Cortical and trabecular bovine femur bones were deproteinized using 6% NaOCl (37, 50, 60°C). kinetic parameters (rate constant activation energy) calculated, surface area each type was considered. A statistical analysis rate constants shows that cortical deproteinizes at a lower than trabecular. energy is higher for bone, no significant differences are found in protein concentration values both bones. Therefore, although cortical, requires more deproteinization reaction to take place. Considering types constituted by mineral, protein, water; work individual inner matrix architecture bones, along with characteristics such as mineral its bonding collagen fibers, may be responsible factors control depletion.
