This phosphatase has also been shown to cleave DNA. Acid phosphatase (AP) is an enzyme that catalyzes the hydrolysis of phosphate esters in an acidic environment. This phosphatase has also been shown to cleave DNA. In this experiment, you purify the enzyme Acid phosphatase from wheat germ. The acid phosphatase reaction has now become an indispensable chemical test in the hands of a forensic scientist to identify the presence of semen which is an abundant source of the enzyme acid phosphatase (1). As ALP is most abundant in the bones and liver, elevated ALP levels are generally a sign of a liver or bone condition. An obstruction of the liver or damage to it will cause ALP levels to rise. This will also occur if there is an increase in bone cell activity. Gaucher Disease: Tartrate Resistant Acid Phosphatase (TRAP) Enzyme Activity, Serum. Hence the test can be used as a tool to detect the presence of acid phosphatase substrate on the offenders' clothes, carpets, floors and vaginal and rectal parts of the victim.

Acid phosphatase: An enzyme that acts to liberate phosphate under acidic conditions and is made in the liver, spleen, bone marrow, and prostate gland.Abnormally high serum levels of acid phosphatase may indicate infection, injury, or cancer of the prostate. Acid phosphates test (ACP), also known as prostatic acid phosphatase (PAP), is an enzyme found primarily in the prostate gland. Phosphate monoester + H2O -->/<-- alcohol + phosphate. A phosphatase is an enzyme that removes a phosphate group from its substrate by hydrolyzing phosphoric acid monoesters into a phosphate ion and a molecule with a free hydroxyl group. Prostatic ACP (PSAP) is produced by the prostate. Although the postpubertal prostatic epithelial cell contains a uniquely high concentration of acid phosphatase, cellular components of bone, spleen, kidney, liver, intestine, and blood also contain this enzyme. The Acid Phosphatase (AP) Brentamine test for the presence of semen is detected either by direct testing or indirect testing of a questioned extractor on a surface for the presence of semen. The PA phosphatase reaction was first characterized in Prostatic acid phosphatase needs to be differentiated from the non-prostatic sources like RBCs source. Acid phosphatase is a lysosomal enzyme, so the prostatic enzyme is found in the lysosome of prostatic epithelium and is a glycoprotein. The released p-nitro-phenol is yellow in colour in alkaline medium and is measured at 405 nm. Acid phosphatases (APs) are a family of enzymes that are widespread in nature, and can be found in many animal and plant species.

Typically, the more Prostatic Acid Phosphatase found in a sample of semen is a sign of prostate cancer. The ability of this enzyme to dephosphorylate phosphoesteres and the observed magnitudes of the kinetic values are consistent with those obtained for acid phosphatase from other sources [33, 31]. It is suggested that the origin of acid phosphatase elevation is bone osteoclasts rather than cancer tissue, as is the case with prostatic carcinoma. It removes a chemical group, called a phosphate, from its parent molecule; Acid phosphatase is found in structures called lysosomes that are present in immune cells. The acid phosphatase test forensics helps in the identification of seminal stains in rape cases.
