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!

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.

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.

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.

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.

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.
