How can we improve the understanding of phosphatase activity in soil?
However, a better under standing of enzymes. A better understanding of the role of phosphatases in soil can be gained et al. 2011). and by using the quantitatively most important soil organic P esters as substrates. decomposition of organic matter (Schimel and Weintraub 2003). However, the

What is acid phosphatase (AP)?
Acid phosphatase (AP) which is derived from the prostate has a pH optimum of the range of 5 to 6. The greatest concentration of AP activity occurs in the liver, spleen, milk, platelets, bone marrow, red blood cells, and the prostate gland. The prostate is the richest source. The majority of AP arises from the RBCs and prostatic tissue.
What is the optimum pH of acid phosphatase?
Acid phosphatase (AP) which is derived from the prostate has a pH optimum of the range of 5 to 6. The greatest concentration of AP activity occurs in the liver, spleen, milk, platelets, bone marrow, red blood cells, and the prostate gland.
What is the purpose of the phosphatase test?
Charm phosphatase tests enable dairies and food processors to quickly and easily make sure that milk is fully pasteurized. The absence of alkaline phosphatase in milk is an indicator that milk has been held at the correct temperature and for the correct time to be fully pasteurized.
What is the principle of phosphatase test?
Test principle Alkaline phosphatase induces the hydrolysis of p-nitrophenyl phosphate in an alkaline solution, and forms a yellow colored complex whose intensity, measured at 405 nm, is directly proportional to the concentration of ALP in the sample.
Which indicator is used in phosphatase test?
The chemical stability, solubility, and rate and intensity of color development indicate that CQC is more suitable for use as an indicator for phosphatase testing than is BQC. It should receive preference in the future.
Which substrate is used in phosphatase test?
This test used disodium phenyl phosphate for the phosphoric ester as substrate in place of the sodium B~glycerophosphate reported in (6). This new substrate is hydrolyzed faster by the phosphatase than is the glycerophos- phate.
What is the definition of phosphatase?
Definition of phosphatase : an enzyme that accelerates the hydrolysis and synthesis of organic esters of phosphoric acid and the transfer of phosphate groups to other compounds: a : alkaline phosphatase.
What are the methods for ALP determination?
The methods currently used to measure ALP activity are the AMP (2-amino-2-methyl-1-propanol) method, the DEA (diethanolamine) method, and the MEG (N- methyl-D-glucamine) method.
What is the treatment for high alkaline phosphatase?
Reduction in serum alkaline phosphatase levels by treatment with active vitamin D (alphacalcidol) in primary and secondary hyperparathyroidism and in euparathyroid individuals.
What is acid phosphatase test?
The acid phosphatase (AP) test is a routine assay used to screen casework items for the possible presence of semen. This colour test is carried out on filter paper which is retained after testing. Two-year-old AP test papers were found to contain sufficient DNA for short tandem repeat (STR) profiling.
What is the function of alkaline phosphatase?
ALP is an enzyme found in your bloodstream. It helps break down proteins in the body and exists in different forms, depending on where it originates. Your liver is one of the main sources of ALP, but some is also made in your bones, intestines, pancreas, and kidneys.
Which of the following substrate is used in alkaline phosphatase test *?
Substrates for Alkaline Phosphatase Nitroblue Tetrazolium (NBT) is used with the alkaline phosphatase substrate 5-Bromo- 4-Chloro-3-Indolyl Phosphate (BCIP) in western blotting and immunohistological staining procedures.
What is acid phosphatase enzyme activity?
Phosphatases catalyze removal of a phosphate group from different substrates. Within a living cell, acid phosphatases are lysosome localized enzymes, and are activated when the lysosome fuses with an endosome. The optimal pH for acid phosphatase activity is usually in the acidic range.
Which buffer is used in alkaline phosphatase test?
For alkaline phosphatase, Tris HCl has been reported as a suitable buffer for maximum activity (Hethey et al. 2002).
