Acid phosphatase

Acid phosphatase is an enzyme that works under acid conditions and is made in the liver, spleen, bone marrow and the prostate gland. Abnormally high serum levels of the enzyme may, for example, indicate prostate disease (infection, injury, or cancer).

ac·id phos·pha·tase (asґid fosґfə-tās) [EC 3.1.3.2] an enzyme of the hydrolase class that catalyzes the cleavage of orthophosphate from orthophosphoric monoesters under acid conditions. The enzyme is found in mammalian liver, spleen, bone marrow, plasma and formed blood elements, and prostate gland. The determination of serum acid phosphatase activity is an important diagnostic test. Called also phosphomonoesterase.
