phosphatase

 [fos´fah-tās]
any of a group of enzymes capable of catalyzing the hydrolysis of esterified phosphoric acid, with liberation of inorganic phosphate, found in practically all tissues, body fluids, and cells, including erythrocytes and leukocytes.
acid phosphatase see acid phosphatase.
alkaline phosphatase see alkaline phosphatase.

phos·pha·tase

(fos'fă-tās),
Any of a group of enzymes (EC 3.1.3.x) that liberate orthophosphate from phosphoric esters.
See also: phosphohydrolases.

phosphatase

/phos·pha·tase/ (-tās) any of a group of enzymes that catalyze the hydrolytic cleavage of inorganic phosphate from esters.

phosphatase

(fŏs′fə-tās′, -tāz′)
n.
Any of numerous enzymes that catalyze the removal of phosphate groups by hydrolysis of phosphate ester bonds. They act in the opposite manner to kinases and are important in metabolism and cell signaling.

phosphatase

[fos′fətāz]
an enzyme that acts as a catalyst in chemical reactions involving phosphorus. It is present in serum, semen, the kidney, and the prostate. It is essential in the calcification of bone. See also catalyst, enzyme.

phos·pha·tase

(fos'fă-tās)
Any of a group of enzymes (EC sub-subclass 3.1.3) that liberate inorganic phosphate from phosphoric esters.

phosphatase

An enzyme that removes phosphate groups from a molecule.

phosphatase

an enzyme that catalyses the release of phosphate from a molecule. For example, in the mammalian liver phosphorylated glucose can be broken down to glucose with a phosphatase enzyme. see GLYCOGEN.

phos·pha·tase

(fos'fă-tās)
Any of a group of enzymes (EC sub-subclass 3.1.3) that liberate inorganic phosphate from phosphoric esters.

phosphatase(s) (fos´fətās),

n a group of enzymes that are distributed throughout most cells and body fluids and are characterized by their ability to hydrolyze a wide variety of monophosphate esters to alcohols and inorganic phosphate.
phosphatase, acid,
n a group of phosphatases (e.g., serum, liver, prostate) with optimal activity below a pH level of 7. Elevated serum levels have been observed in metastatic breast and prostatic cancer; Paget's, Gaucher's, and Niemann-Pick diseases and in myelocytic leukemia.
phosphatase, alkaline,
n a group of phosphatases (e.g., serum, liver, bone) whose optimal activity ranges near a pH level of 9.8. Elevated blood levels occur in Paget's disease and pregnancy, whereas low levels are characteristic of dwarfism and a generalized nutritional protein deficiency.

phosphatase

any of a group of enzymes capable of catalyzing the hydrolysis of esterified phosphoric acid, with liberation of inorganic phosphate, found in practically all tissues, body fluids and cells, including erythrocytes and leukocytes.

acid phosphatase
a lysosomal enzyme that hydrolyzes phosphate esters liberating phosphate, showing optimal activity at a pH between 3 and 6; found in erythrocytes, prostatic tissue, spleen, kidney and other tissues.
alkaline phosphatase
an isoenzyme showing optimal activity at a pH of about 10; found in bone, liver, kidney, leukocytes, adrenal cortex and other tissues, often used in clinical diagnosis of liver and/or bone damage. Called also AP; see also alkaline phosphatase.
phosphatase inhibitor-1
inhibitor of phosphatase enzymes known to activate glycogen synthesis or inactivate glycogen breakdown. Need to themselves be phosphorylated by cAMP-dependent kinases before they are effective in their inhibitory activity.

The teachers also stated that PLAP involves a lot of work at the planning as well as the implementation stage.
Each class has not less than 40 pupils and I have to take all these children for PLAP.
The teachers also lamented the fact PLAP interferes with departmental and ministerial expectations.
They are of the opinion that children should be physically sent back to their appropriate level regardless of their ages or that they should be streamed and put in a class where they are given PLAP until they catch up with their peers.
The researchers also discovered that teachers do not fully understand the concept of PLAP.
For example, one teacher teaching a form 1 class stated that he was having problems giving PLAP lessons to his class as some of them needed concepts from as far back as grade 5 and he did not know how to help them.
Another challenge that came to light relates to lack of materials with which to implement PLAP.
PLAP has been met with negative attitudes by both teachers and students.
It was also revealed that some schools are being supported financially by some donor agencies like Plan International and Norwegian Refugee Agency in the implementation of PLAP.
Some of the teachers also cited lack of cooperation on the part of the students who felt that others laughed at them upon being identified as PLAP students.
