The enzyme alkaline phosphatase (ALP, alkaline phenyl phosphatase, also abbreviated PhoA) is a phosphatase with the physiological role of dephosphorylating compounds. The enzyme is found across a multitude of organisms, prokaryotes and eukaryotes alike, with the same general function, but in different structural forms suitable to the environment they function in. Alkaline phosphatase is found ...
In experiential studies, isoenzymes, which are distinct forms of alkaline phosphatase generated by these tumors, can raise the total volume of alkaline phosphatase in the blood. The Regan isoenzyme [ clarification needed ] [ 13 ] is one of the best studied [ clarification needed ] of these isoenzymes that is linked to several human cancers.
In human serum, the bone ALP (BALP) and liver ALP isoforms are the most abundant TNAP isoforms, in approximately a 1:1 ratio, comprising more than 90% of the total ALP activity. The remaining circulating ALP activity, 1–10%, is attributed mostly to intestinal ALP (IALP). Several different analytical methods for separation and quantification ...

Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. [1] Poor nutrition is a chronic problem often linked to poverty, food security , or a poor understanding of nutritional requirements. [ 2 ]
In contrast, low levels of ALP is found in hypothyroidism, pernicious anemia, zinc deficiency, and hypophosphatasia. [6] ALP activity is significantly increased in the third trimester of pregnancy. [11] This is due to increased synthesis from the placenta as well as increased synthesis in the liver induced by large amounts of estrogens.
Specific activity gives a measurement of enzyme purity in the mixture. It is the micro moles of product formed by an enzyme in a given amount of time (minutes) under given conditions per milligram of total proteins. Specific activity is equal to the rate of reaction multiplied by the volume of reaction divided by the mass of total protein.
The Bodansky unit is an obsolete measure of alkaline phosphatase concentration in blood. It is defined as the quantity of alkaline phosphatase that liberates 1 mg of phosphate ion during the first hour of incubation with a buffered substrate containing sodium β-glycerophosphate. [1]
