Antagonism (chemistry)
Chemical antagonists impede the normal function of a system. They function to invert the effects of other molecules.[1] The effects of antagonists can be seen after they have encountered an agonist, and as a result, the effects of the agonist is neutralized.[2] Antagonists such as dopamine antagonist slow down movement in lab rats.[3] Although they hinder the joining of enzymes to substrates, Antagonists can be beneficial. For example, not only do angiotensin receptor blockers, and angiotensin-converting enzyme (ACE) inhibitors work to lower blood pressure, but they also counter the effects of renal disease in diabetic and non-diabetic patients.[4][5] Chelating agents, such as calcium di sodium defeated, fall into the category of antagonists and operate to minimize the lethal effects of heavy metals such as mercury or lead.[6]
In chemistry, antagonism is a phenomenon wherein two or more agents in combination have an overall effect that is less than the sum of their individual effects.
