== Medical, et al, section ==
==Stereospecific numbering==
I noticed that my addition of information about sn-nomenclature was removed/reverted with the statement: "NOTTEXTBOOK and pedantic".


Claims there is no topical treatment for 3rd degree burns. Hmmm. Children's Hospital of Philadelphia's web-article on 3D burns claims in the treatment section that treatment may include "antibiotic creams or ointments" (which by definition are topical). The false or at least certainly misleading claim (misleading since AB treat or prevent infections subsequent to a 3DB rather than the damage itself, but since it is part of the treatment (in some cases) and aids in healing, that distinction is almost impossible to justify). This article is not about burns, and I suggest the false and quite unnecessary claim be removed.] (]) 08:50, 30 July 2022 (UTC)
I added a section on stereospecific numbering and naming as this is very important in understanding the nomenclature of plasmalogens. The stereospecific nomenclature is not adequately explained on any of the existing Misplaced Pages pages and most appropriately fits within the page on glycerol, since glycerol-derived biochemicals are almost always described using the sn (stereospecific numbering) system.


:You're correct. Someone must have misinterpreted the source, which at the end correctly says that no ''dressings'' have been approved for third-degree burns. The source, I might add, is a press release for a glycerin-based dressing for use in first and second-degree burns, but you can't dress a third-degree burn because that would be like putting a bandage on gangrene. The dead and dying tissue has to be removed and new skin grafted into place. But topical ointments and gels? Sure, those have to be used. So I say go ahead and remove the sentence. You can easily do that yourself. Just leave a little edit summary at the box at the bottom pointing people to this discussion. ] (]) 20:32, 30 July 2022 (UTC)
I added background on the numbering system itself to show why the numbering system exists and why it is necessary.

== Confusion about exact nature of glycerol and glycerin ==
The Misplaced Pages styles regulations regarding "writing like a textbook" were not violated.
Facts were presented, but not in a style to "teach subject matter".
I did not have:
# leading questions
# systematic problem solutions as examples


It seems that according to this Misplaced Pages article, glycerin and glycerol are exactly the same thing and that glycerol is a viscous liquid. However, I have read somewhere that glycerin is actually 5% water. I have also been told by someone that pure glycerol is actually a powder. Does anyone here know the authoritative truth about these things? ] (]) 13:25, 3 June 2023 (UTC)
It may have been pedantic, which is a negative way of saying I was precise and meticulous, but I don't see that being a pertinent problem in any of the Misplaced Pages style guides. Furthermore, the edit shouldn't have been removed -- but the pedantic nature could have simply been edited out (if that was the problem). When information is missing, and someone adds it to a page, I don't think the solution is to remove the needed information, even if it isn't written 100% to par (but I am new to this)

== Glycerol Toxicity ==
I admit that I am new to this, and open for a more detailed reasoning for the removed edits, as well as suggestions to improve my writing style, but the information is a needed addition to Misplaced Pages.


The claim that it is "non-toxic" is apparently false. There are cases of glycerol toxicity in children who consume too much of it - typically in slushies (?) that use excessive glycerol (more than a typical recipe containing glycerol as a texture additive or sweetener substitute) to maintain a liquid state. Less info is available on whether it ever affects adults, but it has caused hypoglycemia and unresponsive unconsciousness in small children which is diagnosed as "glycerol toxicity" thereby indicating it is not in fact non-toxic. ] (]) 14:17, 31 January 2024 (UTC)
For now, I am re-adding the information
] (]) 05:06, 25 July 2016 (UTC)


:Glycerin generally is considered non-toxic, with the word "toxic" generally reserved for poisons. Just about anything is bad for people if taken in excess. For example, water is typically considered to be the least toxic substance known, but even water can be overdosed on, which causes death very rapidly. (See: ]) Still, it's not a poison in the usual sense and in normal doses is considered non-toxic. Glycerin is similar. It probably wouldn't hurt to add some information on the possibility of overdosing on glycerin, but in general it's not a poison but a food substance, so I think describing it as non-toxic is still correct. ] (]) 18:30, 31 January 2024 (UTC)

:: Glycerol doesn't meet any definition of toxic substance. Non-toxic does not mean non-harmful. If you consume oxygen, water, salt, sugar, or anything else, in excess it can result in injury. The LD50 of oral glycerol is >20g/kg, which is more than other common non-toxic substance like table salt. The therapeutic dose, when used as an osmotic diuretic, is 1.5g/kg per dose every 4h. For your standard 10kg 1 year old that is about two teaspoons (11ml) per dose (that is enough to cause a mild increase in urinary output). Rats given 10g/kg per day per year suffered no ill effects. Chronic exposure adverse effects are mostly due to its caloric effects--it is usually completely absorbed within 30 minutes of ingestion and is metabolized like simple sugars. <!-- Template:Unsigned --><small class="autosigned">—&nbsp;Preceding ] comment added by ] (] • ]) 19:49, 1 March 2024 (UTC)</small> <!--Autosigned by SineBot-->

== Glycerin smoking ==

Electronic cigarette use is technically not 'smoking' - there is no combustion. The process is considered vaporizing or atomizing.
