Welcome!
Hello, REDABE, and welcome to Wikipedia! My name is Ian and I work with the Wiki Education Foundation; I help support students who are editing as part of a class assignment.

I hope you enjoy editing here. If you haven't already done so, please check out the student training library, which introduces you to editing and Wikipedia's core principles. You may also want to check out the Teahouse, a community of Wikipedia editors dedicated to helping new users. Below are some resources to help you get started editing. If you have any questions, please don't hesitate to contact me on my talk page. Ian (Wiki Ed) (talk) 16:38, 14 October 2016 (UTC)

{| width="100%" cellpadding="0" cellspacing="5" style="vertical-align:top;" ! Antagonism (chemistry) [A critique]

From Wikipedia, the free encyclopedia

This article needs additional citations for verification. Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (December 2012) (Learn how and when to remove this template message) 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.

The word is most commonly used in this context in biochemistry and toxicology: interference in the physiological action of a chemical substance by another having a similar structure. For instance, a receptor antagonist is an agent that reduces the response that a ligand produces when the receptor antagonist binds to a receptor on a cell. An example of this is the interleukin-1 receptor antagonist. The opposite of antagonism is synergy. It is a negative type of synergism.

Experiments with different combinations show that binary mixtures of phenolics can lead to either a synergetic antioxidant effect or to an antagonistic effect.[1]

Appropriate /Reliable Reference There's only one reference listed here, but yet again there's only 3 paragraphs on the page.The link takes you to a partial research paper; partial in the sense that one must pay to view the remainder of the paper. So, it reliability is questionable since the review/research paper is not entirely visible.

Information Source No information on this is given. There is just a link to semi- review/research article and links to other Wikipedia articles.

Relevance Although the article is a chemistry related stub ( it even says so in the title) the page ends with Antagonism's use in toxicology as well as in biochemistry.

Future Additions ° Expand on History/Background of topic ° Usage ° Include more/ accessible references & citations ° Include a viewpoint that supports the chemistry behind Antagonists
