Degradation slowing

Carstensen directly relates the level at which degradation slows to the amount of water present in the matrix and utilizes this equilibrium level, denoted A, in further kinetic analysis. Kinetic treatment of the data reveals a first order decay character to the degradation, with a linear slope of the log of the thiamine hydrochloride concentration at a specific point (A) in relation to the observed equilibrium level (A ), with respect to time in days.

Elimination of unwanted proteins is just as important as synthesis of desirable proteins. The stability of cellular proteins varies over a wide range. Some unstable proteins have a half life of minutes, while others survive almost as long as the cell. A short half life simplifies the rapid control of protein concentration by synthesis or degradation. For example, in nondividing cells, ornithine decarboxylase is normally synthesized and degraded rapidly. When such cells are stimulated to proliferate, ornithine decarboxylase degradation slows down, resulting in a net increase in the concentration of ornithine decarboxylase protein.

Concerning the biodegradation of HAp, there are reports in the case of no degradation, slow or partial degradation and for the degradable case. The differences in these results are dependent on the experimental conditions such as the characteristics of the materials, animal species, implanted sites and methods of observation.
