Talk:Nitric oxide

message: Hi Everyone! I am thinking of adding some sources and additional information to the biological effects section about Nitric Oxide's role in cell signaling. Some of the secondary and tertiary sources I am thinking of including are:   
T., Hancock, John (2010). Cell signalling (3rd ed ed.). Oxford: Oxford University Press. ISBN 9780199232109. OCLC 444336556.
and 
 Ribeiro, Victor Pena; Arruda, Caroline; Abd El-Salam, Mohamed; Bastos, Jairo Kenupp (2018-01). "Brazilian medicinal plants with corroborated anti-inflammatory activities: a review".

Let me know what you think.

message: NO + O2 reaction, is it "rapid" or "a very slow process"?? In the wikipedia article "nitrogen dioxide" it is stated that "Nitric oxide can be oxidized in air to form nitrogen dioxide. At normal atmospheric concentrations, this is a very slow process." while in the article "nitric oxide" it is stated that "nitric oxide is rapidly oxidised in air to nitrogen dioxide." WHICH IS TRUE??  — Preceding unsigned comment added by Krzysztof Bohdan (talk • contribs) 00:16, 21 May 2015 (UTC)

message: The opening paragraph talks about NO being toxic but, down in the biological effects section, it is described as a muscle relaxant, vaso-dialator, etc.
I'm not clear what the "toxic" part is.  Is NO more or less toxic than, say, Valium?  I don't think "toxic" is used appropriately, here; should probably be replaced with "undesirable."
:I disagree,  toxic is the correct term here.  As stated in the article, the effects of NO can be toxic if the production is at high levels &/or sustained.  In the laboratory, this can be studied and indeed the chemical reactions of NO are different at different concentrations (non-specific damaging event occurring at high concentration such as might occur during an inflammatory or ischaemic event eg stroke). I will try to find a reference for this.JustAnotherKinase (talk) 18:56, 6 July 2010 (UTC)

message: How does the oxygen bond to the nitrogen? I´ve learned the oxygen can only have two covalent bonds, and the nitrogen, three. If two electrons from each are in the bond, the nitrogen doesn´t have its octet complete. What happens, then? A.Z. 14:51, 2 November 2006 (UTC)

message: Minoxidil apparently works directly on ATP-sensitive potassium channels without stimulating cGMP or PKG. The Potassium hypothesis for hair growth has been supported by numerous agents that influence potassium flux altering hair growth. It appears to be direct on the dermal papillae and potassium channels, and not increased blood flow or PKG phosporylation cell signalling events. As far as NO and the hair follicle it is inducible by androgens and is present in follicle melanocytes (role in greying maybe) but I don't think it is exactly clear what role it plays (maybe associated with hair loss). I don't think the statements are accurate and upto date or appropriate for the topic of NO. Minoxidil maybe contains the molecular structure of NO but there is no proof that is how it effects hair growth. GetAgrippa 05:06, 4 February 2007 (UTC)

message: How do we get the importance of this page rated?  It desperately needs this as this is a critical biological mediator and is key to regulating blood pressure and the prevention of atherosclerosis.  Indeed, the importance of NO was highlighted in 1998 when Robert F Furchgott, Louis J Ignarro and Ferid Murad were awarded the Nobel Prize for Physiology or Medicine for work that led to the discovery of NO as a biological mediator.  NO even has it's own peer-reviewed journal.

message: The 3rd sentence of the second paragraph reads: However, sustained levels of increase NO production result in direct tissue damage and contribute to the vascular collapse associated with septic shock, whereas chronic expression of NO is associated with various carcinomas and inflammatory conditions including juvenile diabetes, multiple sclerosis, arthritis and ulcerative colitis.[2]
The reference is: http://www.ncbi.nlm.nih.gov/pubmed/9366709
Simply put, this sentence is not supported by the reference and the sentence does not appear to be a confirmed fact. Millions of people around the world supplement with Arginine and Citrulline to boost NO levels in the body without any of these alleged negative issues.  —Preceding unsigned comment added by 63.207.68.169 (talk) 22:24, 11 February 2011 (UTC)
replies: text: Yes, you are right—the reference refers only to a mechanism of tissue damage. I've moved the reference within the sentence accordingly, and marked the rest of the sentence as "citation needed". But let me point out here that oral arginine and citrulline are unlikely to significantly increase tissue levels of NO, and tissue damage occurs at NO levels altogether higher than those that dietary supplements would be likely to elicit. --Tryptofish (talk) 22:50, 11 February 2011 (UTC)

message: I think that the word "diatomic" should be changed to "binary", to me diatomic signals diatomic elemental forms, such as 
:O2 , N2, Hg2, H2, etc. 
This could lead to some confusion for people who don't completely understand diatomic elements. Of course i may be wrong! NO is a binary molecular compound, and while being diatomic, I feel that anyone who is beginning their study of chemistry could be confused by it. 
SaiferPhoenix (talk) 23:08, 20 March 2011 (UTC)
replies: text: While term "diatom" does refer to a molecule consisting of two atoms of the same element, like those you mentioned, the adjective "diatomic" can technically be used to describe any molecule consisting of exactly two atoms. However, you make an excellent point about how that might get confusing, and in this sense "binary" is practically interchangeable with "diatomic", since "binary" describes any molecule made up of two non-metallic atoms (to the best of my knowledge.) I second this argument, and since it's reasonable enough, I've changed the sentence accordingly. Wikipedia asks it's users to edit "boldly", but I'm still rather new here, and if anyone has reason to say this change was rash, by all means, revert it.--SRGPaladin (talk) 05:12, 10 December 2011 (UTC)
replies: text:  We all learn this way. Binary compounds technically contain two elements, and thus at least two atoms, but perhaps more.  For example, water is a binary compound and is triatomic. So I'm afraid you're stuck using the exact word diatomic if you want to mean "two atom molecule". I've left it as "binary diatomic", which is exact. SBHarris 01:35, 24 April 2012 (UTC)
thread_title: Possibly Confusing Terminology?

message: The infobox designates the IUPAC name of this compound as "nitric oxide". Shouldn't the IUPAC name of this element be "nitrogen monoxide", or is there a special exception for this compound? I am not arguing for the title of the article to be changed, only the part of the infobox with the IUPAC name. T.c.w7468 (talk) 22:06, 2 September 2012 (UTC)
