I feel like I'm gonna cry because I just realized that I grew up with this channel in 2016 I used to turn on this channel to help me with my math homework in high school to 2019 for my SAT and now I study medicine and use it to help me with biology class, whoever runs this channel, İ appreciate your work and I wish you the best, thank you so much, sir.
Dude, I used your channel religiously back in 2017 for GenChem. Now I am back in 2019 for Physical chemistry, brushing up on old topics. I just want to say it makes me so happy to see you at over 1 million subscribers. The growth over the past 2 years has been insane!
I am here again, from your calculus to physics passing by chemistry, I mean where you should I go. You literally stole my attention, I am not even paying attention to my professors anymore, because I know I have a better one on TH-cam name organic chemistry tutor. Just thank you
hey guys I'm really struggling with chemistry cause I didn't get to do it in high school what but through his explanation I'm starting to understand I bit of chemistry
3:17 ".. but in glucose, it is pointing down". On the drawing, the right side of glucose is pointing down, and on the galactose is not. Is that the other difference they have in 3D?
When you start with an innocent trivia question about sugars among friends, ( no cheating with phones) and afterwards end up wanting to learn more, you realize that no one in the spontaneous discussion you had the night before, including yourself, knew what the old heck we were talking about. Thanks, smart people, for being there.
What about the hydroxyl group on C-1 of galactose? Is it a beta group as opposed to alpha in the structure of glucose? What I mean is, glucose and galactose differ each other by not only C-4 but also C-1. Is it correct?
Because glucose has two forms i.e alpha and beta. In beta form, OH group is upwards and in the alpha form, OH group is downwards, on carbon 1. The structure in the video is alpha glucose but if we take beta glucose then the carbon 1 atom of glucose will be same as galactose. Thus, the only difference between glucose and galactose in beta glucose is in Carbon 4. I think it's either a debate whether alpha or beta is correct OR glucose comes in two forms. That's why we don't think about alpha glucose being too different and just ignore it.
Glucose has two forms. Alpha -glucose and Beta-glucose, depending on the position of the OH at C1. Down=Alpha. Up=Beta. So it is still glucose when you consider C1. The emphasis is at C4; where the position of the OH determines where it is glucose or galactose.
I just checked my text... It is at carbon 4.. (main difference between glucose and galactose for anybody reading)... I'm sorry you're awesome, but you are inverted at carbon 1) I'm not sure if you made a correction on a later video but might want to fix this somehow. I'm a science dork not a tech dork. YOU'RE AWESOME btw😎
The difference between your and galactose... The way it has drawn (you have drawn) there is a difference at carbon 4, yes. But about the reverse of OH and H on the other side?? Please help
you know for sure you're a poor guy if you need the whole biology playlist to revise for just one unit of your 5-unit school syllabus of just one subject which is biology T-T

@AzuraCendanadie
@AzuraCendanahow you come here to study with all that negativity 😭
@AzuraCendanayou certainly do care enough to reply
@AzuraCendana Just like your parents don't

U made me love chemistry.on behalf of all Nigerian students I say God bless you sir
Please know that you are the most helpful channel on this site. Keep up the good work.
True
I agree with u
Thank you so much! I did not understand anything on what i was reading but this heeelped. Also thank you to the ones who gave extra infos
I am here again, from your calculus to physics passing by chemistry, I mean where you should I go. You literally stole my attention, I am not even paying attention to my professors anymore, because I know I have a better one on TH-cam name organic chemistry tutor. Just thank you
This man help me in every single subjects; maths , biology, chemistry and physics 😭
awesome explanation on the difference with glucose and fructose with the same formula but different structure!
Fantastic, I can practice better my english, because I talk spanish, as my mother lenguage and learn more about this topics
Thank youuuuuu sooooooo much for your useful lectures.
I hope to become a great teacher as you sir!!!!!
hey guys I'm really struggling with chemistry cause I didn't get to do it in high school what but through his explanation I'm starting to understand I bit of chemistry
Try watch more videos
savior why can't my prof just teach like you
3:17 ".. but in glucose, it is pointing down". On the drawing, the right side of glucose is pointing down, and on the galactose is not. Is that the other difference they have in 3D?
Is the The difference between glucose and galactose supposed to be at c-4 alone???
But it seems to be different at c-1 as well
That was an error at C1
thanks alottt, this video helped me. thx so much
Thanks for the leacture

I love science.

You don't include the carbonyl carbon (C1). He's showing glucose as alpha so the OH is down.
at 4:07, I thought galactose only differ at carbon 4, but why is carbon 1 also different?
Because glucose has two forms i.e alpha and beta. In beta form, OH group is upwards and in the alpha form, OH group is downwards, on carbon 1. The structure in the video is alpha glucose but if we take beta glucose then the carbon 1 atom of glucose will be same as galactose.

Even my public health is working🎉🎉🎉
Biology play list developing 😀😀😀
I wish you specified that Fructose carbon order is opposite than Glucose and that the reducing end is on the second carbon.
could you show how fructose transforms to its pyranose form?
I'm very interested thanks ❤❤❤
Why is glucose a six-membered structure and fructose a 5-membered structure?
Alternative title: My teacher's entire class period in 6 minutes.
True😢
Glucose and galactose: the -OH groups attached to C1 point different directions
Glucose has two forms. Alpha -glucose and Beta-glucose, depending on the position of the OH at C1. Down=Alpha. Up=Beta. So it is still glucose when you consider C1. The emphasis is at C4; where the position of the OH determines where it is glucose or galactose.
So "sugar" is a bonding between the elements H, C, and O?
Thankkk u so much 😭😭
thank you sir it was very helpfull
Glucose and Galactose don’t they differ at Carbon-1 as well?
You don't include the carbonyl carbon (C1). He's showing glucose as alpha so the OH is down.
So in deoxyribose, it does not strictly follow the formula CH2O, correct?
yes
what is the name of the compound containing glucose, galactose and ribose?
I just checked my text... It is at carbon 4.. (main difference between glucose and galactose for anybody reading)... I'm sorry you're awesome, but you are inverted at carbon 1) I'm not sure if you made a correction on a later video but might want to fix this somehow. I'm a science dork not a tech dork. YOU'RE AWESOME btw😎
No words 😍
Where did you get the C6H12O6? I mean Carbon is 6 but the Hydrogen is 12? And Oxygen is 8?
c6h12o6 is the original chemical equation for glucose, tho im not sure why oxygen differed by 2, maybe coz of isotopes?
What about sucrose? The sugar most people are familiar with.
wait isn't there supposed to be an aldehyde on glucose and a ketone on fructose?? Where is that??
Have a question..why insulin causes inflammation in the body when it is in excessive
It's because insulin is proinflammatory in nature that's why
Why it's acid "RNA" whereas it's sugar?
Failing is my style man even if I work hard❗
The difference between your and galactose... The way it has drawn (you have drawn) there is a difference at carbon 4, yes. But about the reverse of OH and H on the other side?? Please help
what are these type of diagrams called?
Bharat Mata ki jai....🇮🇳🇮🇳🇮🇳
Ok
Amnt getting well whats HO?
Hydrogen and oxygen
Galactose = Galactic Sugar

It will be better if it is white board and black marker
all that i got from this video is that it's okay for me to cannibalize humans because they taste sweet or 'sumin
