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.
There are many different types of chemical inhibitors. Some of the more common types include corrosion inhibitors, reversible and irreversible enzyme inhibitors, microbial inhibitors and preservatives, and UV stabilizers. Corrosion inhibitors specifically prevent acid or oxidation damage to metals or metal alloys.
