Metaphosphoric acid will inactivate oxidase to prevent loss of ascorbic acid (Kendler)
The formula for metaphosphoric acid is HPO3.
Metaphosphoric acid is often used as a moisture- or water-absorbing reagent. To prepare one-liter of 5 percent metaphosphoric acid, dilute 59 ml of 85 percent metaphosphoric acid with one liter of distilled water.
HPO3 is the chemical formula for metaphosphoric acid, also known as tetraphosphoric acid. It is a polymeric oxyacid of phosphorus that is often used in chemical synthesis and as a reagent in analytical chemistry.
Ascorbic acid (vitamin C) is an antioxidant. It protects the cell against oxidative damage.
Gastric acid determination, also known as stomach acid determination, gastric analysis, or basal gastric secretion, is a procedure to evaluate gastric (stomach) function. The test specifically determines the presence of gastric acid, as well.
Ascorbic acid is vitamin C and has many functions in the organism.
The purpose of the gastric acid determination is to evaluate gastric function by measuring the amount of acid as suctioned directly from the stomach. The complete gastric acid determination includes the basal gastric secretion test.
