Disambiguation link notification for April 3

Hi. Thank you for your recent edits. Wikipedia appreciates your help. We noticed though that when you edited Sushil, you added a link pointing to the disambiguation page Susheela. Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ • Join us at the DPL WikiProject.

Glucoraphanin.png

Hello. The picture you made of glucoraphanin shows a double bond between the rightmost sulfur atom and the oxygen. The non-planarity implies a lone pair on the sulfur. In that case, the sulfur atom has ten electrons around it. In fact, there should not be a double bond between the sulfur and the oxygen, but rather, the sulfur should have a formal charge of +1 and the oxygen a formal charge of −1, with a single bond between them (see Sulfoxide). Can you fix this? Eric Kvaalen (talk) 12:08, 23 June 2017 (UTC)

Eric Kvaalen, citing from the Graphical representation standards for chemical structure diagrams (IUPAC Recommendations 2008)¹: Functional groups containing sulfur, selenium, and tellurium are also preferably depicted with normal single and double bonds and without the addition of extra formal charges, even though such representations will violate the octet rule. The same formalism is used in the recent Blue book from 2013. Therefore in this moment I am not considering to apply the suggested change. Even through I understand and share your sense for precision and correctness. Regards, —Mykhal (talk) 18:08, 24 June 2017 (UTC)

Thanks for your reply. I have just read your link. They explain the problem with the nitro group, and they say that in that case one should use formal charges (or else just write NO
₂). But then they give no explanation or justification why they go the other way with phosphorus and the chalcogens! People of the world, rise up! Eric Kvaalen (talk) 10:07, 30 June 2017 (UTC)

​I agree it seems like inconsistency and tradition. I think one explanation why nitro group notation with two N=O bonds is unacceptable is because it would mean octet rule violation for 1st/2nd periodic table row element, which really is unacceptable, because there are no d-orbitals involved, only s and p. I guess you should be consistent in your fight and promote this single-bond-and-charges-only notation also for e.g. inorganic sulfates, phosphates, etc.. which would then look really wild :) —Mykhal (talk) 11:13, 14 July 2017 (UTC)

​(please note that the last sentence is an example of irony) —Mykhal (talk) 17:04, 14 July 2017 (UTC)

I came back to this picture the other day. Why do you show the methyl sulfinyl group with this chirality? Does it really have this chirality, or is there a mixture of both? In that case we shouldn't show any chirality I think. Eric Kvaalen (talk) 11:17, 21 June 2022 (UTC)

​ I don't remember exactly where did I get the stereochemistry info, but it can be verified e.g. in doi:10.1016/j.phytochem.2008.09.008. I might (re-)dig in deeper later. Regards, —Mykhal (talk) 15:15, 21 June 2022 (UTC)

My silly mistake

The self-link was rightly reverted... what was I thinking? Andrewa (talk) 19:05, 8 October 2017 (UTC)

Oh, admin. I am somewhat sorry for slightly rude action. If the the page contained no info about the alternate self-link name, it could be done little bit more systematically – creating red link by deleting the redirection page. But it contains some info.. so it's debatable what's the right thing. —Mykhal (talk) 19:22, 8 October 2017 (UTC)

That I'm an admin is irrelevant... sorry if I scared you. I stuffed up. We all do at times. Didn't check the preview adequately. I see no rudeness. Thanks for being so collaborative, it's very encouraging! Andrewa (talk) 19:47, 8 October 2017 (UTC)

Bot request (and block)

I don't think you made the request properly; you created the subpage, but you also have to add a link to it to the main page. There are directions at WP:BOTREQ, but if you need help let me know.

I've changed the block reason, as it wasn't spamming. But I left the block in place, both because the blocking admin didn't want to unblock (and I didn't feel like arguing), and because you don't really need it unblocked unless the bot request is accepted, in which case an unblock is easy. --Floquenbeam (talk) 03:37, 20 December 2017 (UTC)

Thanks for the notice, I have then made the missing step of the bot request. Regarding to the block reason, there's still ".. for adding spam links." on the bot's talk page, unfortunately, hardcoded into that semi-HTML infobox. ​ —Mykhal (talk) 07:20, 20 December 2017 (UTC)

Curious edit

I noticed you added the fact that the sample Version 10 QR code is in capital letters, but why only that one? Why not add that comment to all the examples? Or is it even necessary? As all QR codes can contain only capital (or upper case) letters as is stated in the table just above the examples. Just wondering why that one is so special.  :-) Thanks! WesT (talk) 18:59, 2 September 2020 (UTC)

​ This is the only one with all-capital letter text encoded. Better ask the person who encoded upper-case text into that image. I considered a just note after the text instead of correcting the actual text, that would look ugly and rude. Regards, —Mykhal (talk) 19:28, 2 September 2020 (UTC)

​ … Oh, I'm sorry for the inconvenience; after re-reading your post carefully: I did not notice the claim about inability to encode lowercase characters. I am not currently able to verify that claim, anyway it's not related to all modes, as stated. All QR encoders I have used were able to encode text case-sensitively, and of all images in that "gallery" only that one decodes to uppercase text. Regards, —Mykhal (talk) 19:46, 2 September 2020 (UTC)

Interesting...I hadn't tried to scan any of them, just assumed that all were encoded as uppercase (per other places in the article). I know when I scan a QR leading to a webpage it _seems_ to be lowercase, but I assumed (again) that it was due to the application knowing that all websites are lowercase and converting before using it. I'll have to check it out more. Thanks again! WesT (talk) 21:37, 2 September 2020 (UTC)

Deletion of old redirects

If you believe that a redirect which has been in existence for a long time should be deleted, then take it to a deletion discussion. Deletion of the redirects you have tagged is certainly not uncontroversial, and none of the speedy deletion criteria applies to them. The speedy deletion criterion for implausible redirects applies only to recently created redirects for a good reason. You may have checked that there are no internal links from other Wikipedia pages to the redirects, but you can't possibly know that no external links exist. JBW (talk) 08:16, 14 October 2021 (UTC)

I have now realised that I misunderstood the nature of the redirects, and I have deleted them. JBW (talk) 12:46, 14 October 2021 (UTC)

Why was my change reverted?

I notice that you reverted an edit of mine on Trimethylsilyl azide last month. As far as I am aware, "azidotri(methyl)silane" is the unambiguous PIN of the compound. You claim that "Si compounds don't have IUPAC 2013 PINs", but the Blue Book clearly assigns PINs to Si compounds that have at least one C atom, such as "(chloromethyl)silane (PIN)", "chloro(methyl)silane (PIN)", or "(difluoroboranyl)tri(methyl)silane (PIN)". For this particular name, we can go down the P-41 seniority order. Since the compound has no –OH group or chalcogen analogue, it is not an oxoacid (P-67.1.2.4). Since there is no H₃Si(OH) parent compound (P-67.1.2.1–2), it is not an acid pseudohalide. The azide group cannot be used as the parent structure (P-61.7, P-74.2.2.2.2). Therefore, silane is the parent structure, to be modified with substitutive nomenclature. Finally, we add the parentheses in accordance with P-16.5.1.3.1 (emphasis mine):

For mononuclear parent hydrides with two or more substituents the first cited substituent never has enclosing marks unless it includes a locant. The second and further substituents are each enclosed with parentheses even for simple substituents. When the simple substituent groups are accompanied by multiplicative prefixes such as 'di' and 'tri', the multiplicative prefixes are not included in the parentheses.

If you have a different interpretation of the Blue Book, please share it. LegionMammal978 (talk) 00:09, 18 August 2022 (UTC)

​ This ...tri(methyl)... looks very unusual, however there are several occurrences when they have changed to it, as I can see in the errata, I could not found any such construction in the original text. So I was not up-to date, i.e. wrong, and I apologize. Thanks for the info. (I will have to dig into rules more carefully later.) Regards, —Mykhal (talk) 04:23, 18 August 2022 (UTC)

Yeah, lots of the examples in the printed Blue Book are inconsistent with its wording of P-16.5.1.3 and also with each other. I contacted G. P. Moss about it a few times over the years to get all the ambiguity cleared up. Funnily enough, with the rule's original wording and examples, I thought the enclosing marks had to be alternating, e.g., "bromo(chloro)fluroro(iodo)methane"; it appears that the intent of the rule has always been to require "bromo(chloro)(fluoro)(iodo)methane (PIN)". LegionMammal978 (talk) 13:43, 20 August 2022 (UTC)

​ Note: Another reason why I was skeptical is that ACD naming software (free) still does not acknowledge it and still produces names like chloro(trifluoro)methane. —Mykhal (talk) 10:05, 29 July 2023 (UTC)

Technically blocked page-move

Regarding moving Di-pi-methane rearrangement to use the actual "pi" symbol, if you don't think the move itself is controversial but are having some sort of technical problem, you can list it at Wikipedia:Requested moves/Technical requests and those who are able will sort it out. No harm in starting a formal move-request discussion as you did, since that will also be handled by those with the special tools when they close the discussion.

Doesen't the total number of possible proteins seems relevant for the wiki page about proteins?

Doesen't the total number of possible proteins seems relevant for the wiki page about proteins? Claes Lindhardt (talk) 22:13, 2 July 2023 (UTC)

​ You probably relate to your question at Amino acid talk page, which I undid. The reason was that Wikipedia is not a discussion forum, I mean the question seemed rather unanswerable/speculative, and also it was bound to improper article (it's more related to Peptides, Proteins, Protein structure, Structural biology, etc.). Regards, —Mykhal (talk) 15:29, 3 July 2023 (UTC)

But it seems like something a lot of people have already had some very concrete thoughts about: here is someone https://theconversation.com/what-is-a-protein-a-biologist-explains-152870 who estimates that there is around 20,000 different proteins in our body. Is there an article about the types and number of proteins in the human body somewhere? Do you think it would be relevant to the https://en.wikipedia.org/wiki/Human_body article? There is a list of distint skeletal muscles(List of skeletal muscles of the human body) in the human body as well as cell types(List of distinct cell types in the adult human body). So why not a list of proteins occuring in the human body? But it could also make sense to it under something like amino acids as they are what forms the rules for what proteins can come into existence and maybe it is easier and more meaning full to describe the kind of formulas and code from which one derrive the proteins then to list all of them? - Thank you for replying to my initial question, looking forward to hearing your futher thoughts Claes Lindhardt (talk) 10:44, 9 July 2023 (UTC)

There are also other people weiging in on it: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4889822/, https://www.sciencedirect.com/science/article/pii/S0092867420310783, https://www.hsph.harvard.edu/nutritionsource/what-should-you-eat/protein/, https://www.precisionmed.ch/en/what-is-a-protein/ A lot of them seems to lean more towards 10,000 different proteins in the human body Claes Lindhardt (talk) 10:46, 9 July 2023 (UTC)

derivativeFX

Hi Mykhal, as I am only a user that wrote some experiences more than ten years ago, I think I can’t help with derivativeFX. I can confirm that I am also told being allegedly not logged in. I haven’t used derivativeFX for many years. I wasn't even aware of the changes made to my hint page de:Benutzer:Pemu/DerivativeFX.

Currently, as of version from 2022‎-12-3, the page doesn't contain any of my words anymore, so apparently (assuming it isn’t vandalism) there has been some changes to derivativeFX that renders my hints obsolete. If you want to get the spirit of my hints, read older versions of that page. If appropriate, use e.g. deepl.com to translate. It does a nice job, except that it translates "hier" to "here", despite I think "there" would fit better. Also "Durch einen Fehler, der nicht kurzfristig behoben werden kann, könnte er das geänderte Bild nämlich nicht hochladen" should read "Due to a flaw that cannot corrected at short notice, it could not upload the modified image [itself]."
