Fluoride and Alkaline Phosphatase
Since serum alkaline phosphatase increases in fluoride therapy for osteoporosis, it is generally accepted that fluoride stimulates bone formation. However, histochemical studies have shown that alkaline phosphatase is also increased in resorbing osteocytes. Fluoride is toxic to metabolically active bone cells, alkaline phosphatase is released, and serum alkaline phosphatase increases. We propos...
متن کاملChicken Intestinal Alkaline Phosphatase
Purified chicken intestinal alkaline phosphatase is active at pH 8 to 9, but becomes rapidly inactivated with change of pH to 6 or less. Also, a solution of the inactivated enzyme at pH 4.5 rapidly regains its activity at pH 8. In the range of pH 6 to 8 a solution of purified alkaline phosphatase consists of a mixture of active and inactive enzyme in equilibrium with each other. The rate of ina...

inor i8obutanol. Removal of the lipid is accompanied by simultaneous release of the enzyme into true solution. No other organic solvent tested was effective in releasing the bound phosphatase, indicating a unique action of butanol. I wish to thank Dr M. Dixon, F.R.S., for his encouraging interest and advice during this work. This work was carried out while holding a Travelling Scholarship award...
متن کاملAlkaline Phosphatase lsoenzymes
The human alkaline phosphatases constitute a system of multiple molecular forms of enzymes in which heterogeneity is partly due to genetic factors and partly to posttranslational modifications. Recognition of the nature and occurrence of these multiple forms has made a significant contribution both to the understanding of changes in alkaline phosphatase values for serum in disease and to the us...
متن کاملPurification of Alkaline Phosphatase
8. An increase in the rate of progression of the bands down the column decreases the sharpness of the bands. On 'Zeo-Karb 215' (40-60 mesh/in.) a rate ofprogression of 10-15 cm./hr. gave satisfactory results. 9. Equations have been derived permitting the calculation ofthe proportion ofthe column occupied by a component, the width ofthe boundaries and the expected yield of pure components in sep...
