What is it: A Process Control Plan (PCP) is a summary of defect prevention and reactive detection techniques. The overall intent of the PCP is to control the product characteristics and the associated process variables to ensure capability (around the identified target or nominal) and stability of the product over time.
Various compounds can reduce the activity of enzymes. They may act in a variety of different ways, and indeed may be reversible or irreversible inhibitors of the enzyme. An irreversible inhibitor causes covalent modification of the enzyme, so that its activity is permanently reduced.
1 Some Enzyme Inhibitors can be used as Medicines in the treatment of conditions. 2  For example, infection by viruses can be treated by Inhibitors to the viral enzyme Protease, often competitive Inhibitors. 3  This means that viruses cannot build new protein coats and therefore cannot replicate.
