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.
You have to have enough energy to overcome the activation energy barrier (that is to start breaking some bonds). For an energy-absorbing reaction, the activation energy must be at least as big as the energy absorbed (and usually much bigger). For an energy-releasing reaction, it could be as small as zero.Enzymes are, by definition, proteins.I assume you want to know why they are good as catalysts. Among other factors, the complex 3-D shape of a protein makes it possible to physically hold reactants in close proximity to each other. just now. Report Abuse. Proteins are very highly structurally complex, which means within their structure are highly specific 'pockets' which act as active sites for reaction catalysis. These sites can be acidic, basic, hydrophilic, hydrophobic, all depending on the nature of the amino acids inside the pocket.
