<Tr> <Th> NCBI </Th> <Td> proteins </Td> </Tr> <P> Acid phosphatase (EC 3.1. 3.2, acid phosphomonoesterase, phosphomonoesterase, glycerophosphatase, acid monophosphatase, acid phosphohydrolase, acid phosphomonoester hydrolase, uteroferrin, acid nucleoside diphosphate phosphatase, orthophosphoric - monoester phosphohydrolase (acid optimum)) is a phosphatase, a type of enzyme, used to free attached phosphoryl groups from other molecules during digestion . It can be further classified as a phosphomonoesterase . Acid phosphatase is stored in lysosomes and functions when these fuse with endosomes, which are acidified while they function; therefore, it has an acid pH optimum . This enzyme is present in many animal and plant species . </P> <P> Different forms of acid phosphatase are found in different organs, and their serum levels are used to evaluate the success of the surgical treatment of prostate cancer . In the past, they were also used to diagnose this type of cancer . </P> <P> It's also used as a cytogenetic marker to distinguish the two different lineages of Acute Lymphoblastic Leukemia (ALL): B - ALL (a leukemia of B Lymphocytes) is Acid - Phosphatase negative, T - ALL (originating instead from T Lymphocytes) is acid - phosphatase positive . </P>
