Guessing you mean CH ₃−CH ₂−OH, it does tend to help people lighten up and not be so uptight, especially in casual discussions about camera gear! Cheers, let's drink to that!May be with a few drops of CH2-OH ...

You beat me to it by a split second!CH₂−OH is a methanediol subgroup, it cannot exist as a stable molecule. I suspect you mean CH₃−CH₂−OH, aka ethanol.
Best for people not to get their CH₃CH₂OH confused with CH₃COOH though when responding to things written in jest, the latter tends to stifle the sense of humour in forums, and imparts emotions similar to its taste!May be with a few drops of CH2-OH ...
Better still to not confuse it with CH₃OH, because the liver enzyme that converts ethanol to acetaldehyde (which gives you the hangover headache) converts methanol to its corresponding aldehyde, namely formaldehyde (which has effects far more deleterious than a headache). A bit of vinegar isn’t so bad, especially when one is poaching eggs or dressing a salad.Best for people not to get their CH₃CH₂OH confused with CH₃COOH though when responding to things written in jest, the latter tends to stifle the sense of humour in forums, and imparts emotions similar to its taste!![]()
Right!–CH₂−OH is a methanediol subgroup, it cannot exist alone as a stable molecule. I suspect you mean CH₃−CH₂−OH, aka ethanol.
Right!
My chemistry stoped more than 40 years ago!![]()
The enzyme that catalyses the reaction is very interesting in that the hydride transfer step has a contribution from quantum mechanical tunnelling.Better still to not confuse it with CH₃OH, because the liver enzyme that converts ethanol to acetaldehyde (which gives you the hangover headache) converts methanol to its corresponding aldehyde, namely formaldehyde (which has effects far more deleterious than a headache).

With formaldehyde on your poached eggs or salad, they'll never spoil, but flavour might not be so great, and there's the little issue that IARC would probably advise against it on the grounds of it being a group 1 human carcinogen.Better still to not confuse it with CH₃OH, because the liver enzyme that converts ethanol to acetaldehyde (which gives you the hangover headache) converts methanol to its corresponding aldehyde, namely formaldehyde (which has effects far more deleterious than a headache).

Interestingly, there's a drug used against alcohol abuse, disulfiram, which inhibits the enzyme acetaldehyde dehydrogenase that oxidizes acetaldehyde into acetate, causing a build-up of acetaldehyde. If you take it and then drink alcohol, the hangover comes in 5-10 min. Ouch!![]()
Then I guess I shouldn't point out that technically, formaldehyde is a gas and it would be difficult to put on poached eggs or salad unless that gas is dissolved in water to create formalin (in which case it exists mainly as methanediol, CH₂(OH)₂). I say this as someone who has personally on many occasions heated paraformaldehyde (polymerized formaldehyde) powder in phosphate buffer to make neutral buffered formalin."A few new Canon products have been cancelled due to the supply chain issues"
Someone that jumps in to this thread on page 4 will be completely confused.
Ah, perhaps, if you want to be really, really, really specific! I'm not, as we're really pushing it with the chemistry discussion of ethanol and related compounds in a photography gear rumour website!!!Then I guess I shouldn't point out that technically, formaldehyde is a gas and it would be difficult to put on poached eggs or salad unless that gas is dissolved in water to create formalin (in which case it exists mainly as methanediol, CH₂(OH)₂).

Agreed, apologies for going off on a tangent, this thread is about why Canon isn't shipping various cameras and lenses."A few new Canon products have been cancelled due to the supply chain issues"

They go under The Colonials as well, no matter how they spell ... ou parler canadien françaisComplicated by the fact that @Canon Rumors Guy is Canadian.
A most unfortunate use of metaphor of "split hair" when discussing formaldehyde. Aqueous formaldehyde is a protein cross-linking reagent, which will react with then protein keratin in hair, and is unfortunately used in some hair straightening procedures see: https://www.harpersbazaar.com/beauty/hair/advice/a1266/how-keratin-damages-hair/....
On the PubChem Compound Summary page, the compound with the molecular formula CH₂O or H₂CO is listed with the following accepted synonyms: formaldehyde, formalin, methanal, paraformaldehyde, formol, and few more. https://pubchem.ncbi.nlm.nih.gov/compound/formaldehyde
We're both right, depends how fine you like to split hair, for some, whole samples are sufficient, while others prefer to use a microtome!![]()

Canon is no longer “*******”, in fact since the announcement of the RF dual fish-eye, they are *domed*I think you're referring to the "Now Canon is *******" mantra of the Sony fanboy tribal group.![]()
