a measure of the bactericidal activity of a chemical compound in relation to phenol. The test is standardized (Rideal-Walker method, US Department of Agriculture method). The coefficient is calculated by dividing the concentration of the test compound at which it kills the test organism in 10 minutes, but not in 5 minutes, by the concentration of phenol that kills the organism under the same conditions. ...

| phenylalanine hydroxylase |
Phenylalanine hydroxylase (eg. EC 1.14.16.1) is an enzyme which catalyses the reaction causing the addition of an hydroxyl group to the end of the 6-carbon aromatic ring of phenylalanine, such that it becomes tyrosine. Phenylalanine hydroxylase is the rate-limiting enzyme of the metabolic pathway which degrades excess phenylalanine. Mutations in phenylalanine hydroxylase which result in lower activity are the cause of the disease phenylketonuria, or PKU. ...
