I'm just saying something because I have no idea what to say but I don't want to see here empty

Tris

Tris, or tris(hydroxymethyl)aminomethane, or known during medical use as tromethamine or THAM, is an organic compound with the formula (HOCH2)3CNH2. It is extensively used in biochemistry and molecular biology as a component of buffer solutions such as in TAE and TBE buffers, especially for solutions of nucleic acids. It contains a primary amine and thus undergoes the reactions associated with typical amines, e.g. condensations with aldehydes. In medicine, tromethamine is occasionally used as a drug, given in intensive care for its properties as a buffer for the treatment of severe metabolic acidosis...

What does tris-OH look like?

It already has three OH groups

M.A.R.

@CowperKettle you sure it shouldn't be TsOH?

It does have space for more though

CowperKettle

@M.A.R. My Russian sentence says: "Viral inactivation was performed by incubating the solution at pH 3.5 for 30 minutes and neutralizing it to pH=7.5 by adding 1M Tris-OH."

I started googling and started wondering.

But the text should be submitted by Monday, so I better stop wondering and start translating as-is.

For the last 3 days, it has been actual summer in Yekaterinburg.

M.A.R.

Well, I've never encountered it, but it's a possible name

I'd say just go with it

CowperKettle

nods

My friends will go parachute jumping on Saturday, and I was unsure I'd have time, so I refused. Need to translate this..

@CowperKettle this might be worth asking in bio chat

Tris + its conjugate acid is a commonly used buffer, but I've never seen "Tris-OH".

^ And surely this is a troll, right?

M.A.R.

@orthocresol what does either of the images contain? They're blocked for me

But it might be a mis-upload anyway, if it looks funny.

CowperKettle

@M.A.R. Isn't it possible to use some VPN or proxy?

orthocresol

@M.A.R. first image, second image

M.A.R.

@CowperKettle not on this crappy mobile browser

@orthocresol O.o

In November, a new wave of prohibitory legislation kicks in in Russia. It will be forbidden to use proxies and VPNs. And all internet messengers will have to contain built-in features for automatically deleting messages containing "unwelcome" information.

Thus probably some messengers will stop functioning.

I haven't read Russian news for 3 days to get some peace of mind. Maybe I should just read it in portions once weekly. For an hour.

@CowperKettle wow

Melanie Shebel

I saw that. :S

orthocresol

@Zhe I really can't tell if it's a troll.

Melanie Shebel

Okay...

Q: How does a molecule search work by drawing in visual editor?

There are a lot of chemical search engines (such as ChemSpider's Structure search) that allow users to draw and search for a molecule. How does it work? Is the comparison of images used? Could you give me an algorithm or pseudo code?

everytime I post something, I get a downvote, wth

"Is there a proton leak during ATP synthesis?" --- downvote
"Vinegar reacting with metal pan?" --- downvote
"How does a molecule search work by drawing..." --- downvote

Zhe

Happens to the best of us

FTR, I upvoted

I just keep getting them, even on old stuff. I'm just wondering if like there's someone who is serial downvoting me.

orthocresol

No, there isn't.

I just checked.
