ketones in diabetes

What about pokemon? — Preceding unsigned comment added by 70.198.135.109 (talk) 02:44, 11 December 2014 (UTC) Ketones are also a product of body chemistry when the body is under stress. In diabetics, after a sustained period in hypergleacemia (too much sugar in the blood), ketones present in the urine are evidence of advanced disease status.

As noted in the article, diabetic ketoacidosis, this occurs because of prolonged inadequacy of insulin effect rather than "sustained hyperglycemia". alteripse 23:07, 27 May 2006 (UTC)

This needs some solid chemistry attached to it. Something like "In the absence of insulin to convert glucose to energy, mitochondrial cells burn fat cells. This incomplete oxidation results in ketone production. Diabetic ketoacidosis, a potentially deadly condition, results in organ damage from ketones in the bloodstream." There should be many references available, perhaps in Wikipedia, that describe this chemistry. — Preceding unsigned comment added by 192.88.168.1 (talk) 15:00, 28 October 2015 (UTC)

secondary alcohols to ketone

the oxidation of secondary alcohols to ketones does not require strong oxidizing agents. it can be achieved (and in the laboratory, is almost always achieved) with extremely mild reagents. Two common examples are the Dess-Martin oxidation with DMP (Dess-Martin Periodinane) and the Swern Oxidation (Oxalyl Chloride and DMSO).

Agreed. I have greatly revised the synthesis section and included these methods, among others. shultzc (talk) 11:50, 27 November 2008 (UTC)

IPA

Guidance on pronounciation should follow IPA. —DIV (128.250.80.15 (talk) 09:03, 10 April 2008 (UTC))

ketones and aldehydes

Ketones and aldehydes both have a carbonyl group. Why is the difference between them, apart from the carbonyl group being attached to a primary or a secondary carbon? Received the following question today: why is it propanal, in stead of 1-propanone? Could anyone elaborate on the difference between aldehydes and ketones? —Preceding unsigned comment added by 145.102.41.131 (talk) 13:44, 2 March 2010 (UTC)

origin of the name "keton"

"and in fact the word ketone derives its name from Aketon, the German word for acetone.[2]"

This seems to be false information, I couldn't find Aketon as a German word in the "Duden" [www.duden.de], the most comprehensive dictionary of the German languages. Several dictionary books I own and online dictionaries like the German Wiktionary [1] gave no result, either. In Germany we use "Aceton"(sientific) or "Azeton" - the c resp. z are pronounced as (a-TZ-eton), leo.dict.org [2]has an example.85.177.109.124 (talk) 13:53, 19 May 2010 (UTC)

ketones and esters

this page mixes up ketones and esters rather frequently. in one section, it says that ketones are distinct from esters, and in other sections, the carboxyl group of esters are highlighted as examples of ketones.

for the record, esters and ketones are not the same, and should be treated differently. — Preceding unsigned comment added by 199.192.233.65 (talk) 04:11, 19 November 2012 (UTC)

Well I dont see a problem, could you be more specific?--Smokefoot (talk) 13:43, 19 November 2012 (UTC)

Ketones as cellular energy source ("preferred"?)

I've read a few things discussing how the body can use ketone metabolism as an alternative to glucose metabolism - and even claimed by some researchers (Veech in particular) that ketones are preferred by at least some of the body's cells:

Ketosis - Implications from Veech's latest paper - 2012 lay-secondary blog post [[3]]

"Metabolic Effects of the Very-Low-Carbohydrate Diets: Misunderstood "Villains" of Human Metabolism" (2004 [4]

"The therapeutic implications of ketone bodies: the effects of ketone bodies in pathological conditions: ketosis, ketogenic diet, redox states, insulin resistance, and mitochondrial metabolism." (2004) [5]

"Ketoacids? Good medicine?" (2003) [6]

"Ketone bodies, potential therapeutic uses." (2001) [7]

"Medical aspects of ketone body metabolism." (1995) [8]

A generally nicely done introductory article

Stopping by after linking keto groups of steroids to this page, and was very pleased to see it in such fine shape. Kudos to the team keeping it chemically/technically, "encyclopedically", and stylistically spot on. Bravi. Le Prof Leprof 7272 (talk) 01:15, 21 June 2014 (UTC)

Will have a whack at the lede

after discovering the following sentence about the carbonyl being "simple":

• "They are considered "simple" because they don't have reactive groups like -OH or -Cl attached directly to the carbon atom in the carbonyl group, as in carboxylic acids containing -COOH."

This is a concept I have never come across in a couple of decades of university organic teaching and research, which appears to have been a stray addition rather closely "paraphrased" from this web content:

• "They are simple in the sense that they don't have other reactive groups like -OH or -Cl attached directly to the carbon atom in the carbonyl group - as you might find, for example, in carboxylic acids containing -COOH." See REF, [9]

Bottom line, it is not solid encyclopedic content—not acceptable in near quoting the source, or in its URL-only citation, or in the entry level (sixth form at best) nature of this nice, but too basic web content. (With Clayden's OChem, why ever cite such as this?) So, it will be replaced once I have time. Le Prof Leprof 7272 (talk) 04:07, 21 June 2014 (UTC)

If my mind serves me

here are some ketone-containing drugs: acetohexamide, befunolol, daunorubicin, ethacrynic acid, haloperidol, ketoprofen, metyrapone, loxoprofen, naloxone, and naltrexone. Le Prof Leprof 7272 (talk) 04:27, 21 June 2014 (UTC)

Merger proposal: -one -> Ketone

The page -one should be merged with Ketone, as it doesn't make sense to have one single page dedicated entirely to a suffix. If anything, the -one page should just be a paragraph or subsection of Ketone. There is already a Wiktionary page for -one that explains as much as is needed, and I don't think that merging will really affect anything for the negative due to the small size of -one. Johnsnoa (talk) 19:37, 4 March 2017 (UTC)

I created a redirect, as some users may just search for the suffix. Ketone already contains a small chunk talking about the suffix, so it redirects there. --Johnsnoa (talk) 22:07, 4 March 2017 (UTC)

Possible hyperlinks/readability for a layman

This article is pretty incomprehensible for a layman at parts. Some hyper links or explaining what terms mean, especially for the intro e.g. explanations or hyperlinks for “R” “O” etc., would help. Or perhaps a suggestion of how one can begin to comprehend some of this would help. Thanks chemistry magicians.--DonkeyPunchResin (talk) 14:31, 9 March 2020 (UTC)

Perhaps a mention of [[10]] would help. From what I understand R is just shorthand for part of a molecule you don’t need to discuss that is a bunch of carbons and sometimes other stuff. I’ll trust the experts on if/how to edit it though.--DonkeyPunchResin (talk) 14:45, 9 March 2020 (UTC)

And I see the brief explanation given for R in the intro (and I know what O and C are) but R is an odd one and I couldn’t seem to find a wiki page for it. I think there should be one since it appears to be such a ubiquitous term.--DonkeyPunchResin (talk) 15:00, 9 March 2020 (UTC)

Invaluable suggestions. Ketones are part of organic chemistry, a challenging subject typically handled in second year college for majors. So the idea that layman should find this article very comprehensible is maybe asking too much, but we could do better. --Smokefoot (talk) 16:13, 9 March 2020 (UTC)

Good point. A weeding out class so I’ve heard. I do think a Wikipedia page on R in the chemistry sense would be helpful though.--DonkeyPunchResin (talk) 23:49, 13 March 2020 (UTC)

We have R group (chemistry) that is a redirect to Substituent, where it is defined (even with some cite to its original use). It's mentioned in Symbol (chemistry)#Other symbols and Skeletal formula#Pseudoelement symbols. Is the current redirect sufficient, or should that section be spun out into an actual article about "R"? That section omits lots of other pseudoelements (only mentioning R and X, not that even anything else like "M" or "E" or other pseudoelements. DMacks (talk) 03:31, 29 March 2020 (UTC)

Ah! There it is. I suppose the only problem is finding it. I tried searching all around Wikipedia to find out what R was but couldn’t find it. Linking R mentioned here https://en.wikipedia.org/wiki/R#Chemistry would be sufficient I would think. At least I would’ve found it had they been linked. I’ll try and remember to do it in a bit. Thank you--DonkeyPunchResin (talk) 21:53, 29 May 2020 (UTC)

issue with the preview

when you google "ketone", you get in the blurb for the wikipedia page:

> a ketone is a functional group with the structure RCR'

and

> The simplest ketone is acetone, with the formula CH₃CCH₃

these two sentences are of course false, and these organic compounds do not exist.

this is because of the parenthesis around the O's in the article:

> a ketone /ˈkiːtoʊn/ is a functional group with the structure RC(=O)R'

i was scared to edit it and mess something up, but i just thought i'd bring this up here because i feel it could mislead lots of people who don't really know better, like high school students maybe. BetweenCupsOfTea (talk) 10:01, 7 November 2020 (UTC)
