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.
A class of chemicals that interrupt the proper binding of substrates to enzymes are known as inhibitors. They either slow down the process, or they can stop it altogether. Inhibitors in the enzymeâs environment can change its shape so that a substrate no longer fits to it, a process called noncompetitive inhibition.
