What physicians need to know about restrictive covenants. Roy W. BreitenbachThe mention of restrictive covenants provokes an almost visceral reaction among most physicians. But keep in mind these covenants are, for the most part, enforceable.
An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. Since blocking an enzyme's activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors. medicinal enzyme inhibitor is often judged by its specificity (its lack of binding to other proteins) and its potency (its dissociation constant, which indicates the concentration needed to inhibit the enzyme). A high specificity and potency ensure that a drug will have few side effects and thus low toxicity.
We can also study enzymes in the context of activation energy. Many biochemical reactions need a little input of energy to jump-start a thermodynamically favorable reaction. The activation energy is the amount of energy needed for the reaction to go forward and get over its activation barrier. ATP (adenosine triphosphate), the cellâs energy carrier, needs a little help to get over its activation barrier.
