Excellent description of how non-reducing and reducing sugars work. I've had a vague idea of it, but this made it very clear. Thank you!

You just summarized an hour and a half lecture into 11 minutes for me. Thanks for this informative video!

Why can't my professors explain things this clearly? You got me through undergrad and not you're apparently going to get me through dental school as well. Thank you, thank you, thank you!!

after a whole week of class, even rewatching the classes that I recorded and after going for 1 hour group tutoring I could not understand naming glycosidic bonds 'til I watched this. Thank you.

Came here to clear my mind about reducing and non-reducing sugars, was not disappointed. Really good at sharing knowledge easily. Worth the subscription!

Thank you! Your explanation of reducing/nonreducing sugars was exquisite!

God bless your soul. You’ve made gibberish make sense. My professor could never explain like you.

That is exactly what I needed. You are THE BEST TEACHER EVER.

seriously i love you so much clear explanation with perfect tone of voice

you are the best teacher ever

This lecture is very thorough and easy to follow; I subscribed. Thanks!

fantastic lecture! Now I got the difference between reducing sugar and non reducing sugar.

Thank you very much!! your vids always make the best senses to me

so clear and concise -- great lecture!

thank uh very much sir! your videos have always been helpful.

Made it so much clear.literally so much. Sending lots of thanks❤

Please teach my professor how to teach like you! lol finally understood this concept, thank you very much, your videos are always super helpful!

this lecturer is the reason why future physicians will be 🔥🔥🔥🔥🔥

I am watching these as supplement materials while studying year one in medical school. I wish I found these for my MCAT studying!

Really welldone man! you are a savior!! congratz on getting 100k subs soon you truly deserve it!

You are wright

In the previous video you say that reducing sugars are sugars that are capable of being reduced, but in this video you are saying reducing sugars are sugars that act as reducing agents or can be oxidized. I was wondering if you could explain the difference in the definitions.

Perfect. Thank you!

Almost 6 years old video still the best👍

Great explanation...thank you

great lecture!!!!

Thanks for perfect explanation.:)

you're a beast. thank you so much

Simply brilliant

Great Video Thank You!

Thank you for the video. I have a dumb question: How many linkages is possible between two monosaccharides? For example, can we have an alpha 2-4 bond between galactose and glucose? Thank you.

GREAT video Thank you

Hello Sir,I want to know whether the molar ratio of sugar links ( glycosidic linkage) can be calculated through methylation analysis. If so, how to calculate it?

These are the best fucking videos on the web

In the case of sucrose, both of the anomeric carbon atoms are substituted, that is, neither has a free -OH group. The substituted anomeric carbons cannot be converted to the aldehyde configuration and thus cannot participate in the oxidation-reduction reactions characteristic of reducing sugars. Thus, sucrose is not a reducing sugar.

this was the explanation i was looking for!! thx

In your beta-1,4 glycosidic bond with D-galactose and D-glucose, your galactose is incorrect. The -OH groups should be down, up, up, and then the glycosidic bond. This is a minor detail that you should be getting right, instead of confusing others.

@DapaChrons

you're describing D-mannopyrannose. He has it right; Galactose with its -OH groups is up, up, down and then glycosidic bond at the anomeric carbon

Hey Andrey! You mentioned reducing sugars are those that can be oxidised with bromine in presence of water, but doesn't it mean that they are reducible to form alditols? Yes, they can be oxidised as well, but that's not what the term "reducing sugars" means. Please correct me if I'm wrong.

thanks for this awesome lecture, it all makes sense to me now :)

6:00 - Non-reducing sugars

Cab you please explain more on hemiacetal

Please clarify : Out of ALPHA BROMO - D - (+) - GLUCOSE & BETA - (+) - BROMO -D-(+) - GLUCOSE, which one is more stable ? and why?

We meet again. 😂😁👍

Find this lesson exciting

Isn't the OH on the Carbon #1 of the D glucose of the (B-1,4 Glycosidic linkage) supposed to be pointing downward in the drawn figure?

You re right he made one more mistake. In fructose he did not inverted the fructose molecule. If he had done it the oh groups at 3rd and 4th carbon would have been facing opposite direction. Which would have been the right structure of sucrose

@@mid1chosen he has it drawn like in my textbook and on online, although I personally thought it would have been drawn differently.

For a lactose, why is it not a 1,3 bond but a 1,4. If your counting carbons shouldnt you start at the CH2OH

@kannoncrafts7301

The CH2OH is actually the last carbon. Carbon number 1 is located and the functional group. (anomeric carbon)

What is the full name of lactose?

Lol, it seems your domain is biochemistry. I am going to be moving into medicine, and I currently teach biology, but this is way too chemistry heavy for me. Your videos look good, but I am just out of my depth with your material. And nah, perhaps if I stick to them I can learn something right? Or just more brain damage.

Which devilish place produces an accent like this? Never heard anything like it.

You clearly know the material very very well, but if I might, I would recommend you work on your inflection. Your voice goes up and down way too much during a sentence, and your sentences turned in to run-ons far too often and convoluted the information you were conveying.
