ROS are not all bad and not always a byproduct at all. What about ROS production by NOX and DUOX enzymes and their role in immunity? This should be included! Greetings Julia

The whole "antioxidant" thing is food industry / supplement industry jive talk; note how all statements about ROS contain weasel words --- which at one time would have precluded their appearance in the hallowed webpages of Wikipedia. Oh well. But no, really, it's sooooooo retarded ---- mitochondria produce peroxides; peroxides will really mess you up (try getting some in your eye, for example!); therefore ... ROS! Antioxidants to the rescue! Buy this crap, or that crap, because it is HIGH in AntiOxidants!! It's a string of correlations with NO causation in sight. If you want to cite something to me that shows that ROS is bad and antioxidants are good, please, make it something that is in vivo; not something that is strictly in vitro and extrapolated. Thanks.

Does Reactive Oxygen Species increase in matrix ?

Need help ~ up for days

Thanks, v

I believe that there is a higher concentration of ROS in the mitochondrial matrix due to its proximity to the respiratory machinery. LostLucidity (talk) 16:34, 12 March 2008 (UTC)

What about plants?[edit]

This article is currently written from an animal-centric POV. ROS are produced in chloroplasts during photosynthesis and this needs mentioning. Photoinhibition has some details which could be incorporated. Smartse (talk) 15:05, 3 February 2010 (UTC)

I have added a section on singlet oxygen and its importance in plants. Boghog (talk) 14:40, 22 August 2015 (UTC)

ROS = radicals? Table of ROS[edit]

"They are highly reactive due to the presence of unpaired valence shell electrons."

I am not shure, but i do not think this is true. E.g. H2O2 is concidered a ROS but it is not a radical.

I think there should be a table at the begining of the article highlighting important ROS and their reactivity. Due to my crapy english I won`t change anything though..

Helping general readers relate[edit]

ROS are known to the general public as "free radicals?" Or no?

If so, it would help readers get a handle on ROS to give the relationship in the intro.

Something bothers me[edit]

Something bothers me about this article. Is ROS current as a scientific concept? A chemical concept, as opposed to a biological or medical one? The whole article seems subtly aimed at giving a value to them, as if they were optional or a kind of technology, rather than just describing them from a chemical standpoint.

I have added a bit more chemistry and move this up in the article. I hope this helps. Boghog (talk) 14:38, 22 August 2015 (UTC)
