Now I can definitely flip people off saying glucose
I was totally lost on how to memorize those structures, I think you may have just saved me with those tips. Thank you so much! :D
OMG the glucose trick!!!!! haha
Ring Arabian Xylophones Loud (Ribose Arabinose Xylose Lyxose) All Altruists Gladly Make Gum In Gallon Tanks (Allose Altrose Glucose Mannose Gulose Idose Galactose Talose) We had to create a chart of configuration of D-Aldoses and these were the mnemonics taught to us.
I believe the first one should actually be D (-) tetrose
the best mnemotechnique ever
Amazing
thanks!
I like ur pneumonics
Please add videos for advanced organic chemistry for naphthalene,anthracene,etc 🙏..
If you stick out your middle and ring fingers for D-galactose it could be like the spock hand sign from star trek (minus the pointer and pinky fingers), which is a GALACTIC sign of peace i think

Damn.
better mnemonic for D-mannose "Peace Man"
thank you soo much sir g
Why does Glucose ring formation occurs between C1 and C5 (and not like between C1 and C4/C3/C6)
I feel like the voiceover is done by the actor who plays Norman Bates on Bates Motel
Nice
fantastic
thanks a lot i love you
Mannose is would do a peace sign and say "Man" in a hippy way.
Could you explain why two D-glucose molecules look different at 3:52?

the first one says D-gulose, which is a different sugar than D-glucose
Isnt galactose a ketohexose?
the structures for glucose and galactose are wrong, they are epimers on c-4

I'm confused by your comment. They look correct to me? Can you elaborate?

He means both glucose and galactose have same structure but differs at structure at 4th carbon.
.... What is a "threose" ??? :/
great video!!!
Doesn’t the lowest chiral center have an (S) stero here why did you say R?
presence of just one ketone or aldehydes annihilates the possibility of symmetry popping up 😏
9:11 xDD
D ➡😮
Are all D and L molecules enantiomers of each other? (Not just biomolecules)
He said glucose and mannose are diastereoisomers, but wouldn't they be epimers?

All epimers are diastereomers
Am i the only one who doesn't see a man holding a gun for Mannose...?
Glucose not gulose
flipping of means something slightly different in the uk
youre lovely.
You don't have taste like Khan....... but still good just because you are working in khan academy.

I'd say they love galactose
if i drank alcohol for everytime u said "D" i wld be a drunk mofo . great video tho ;)
