YOU ARE AMAAAAAAAAAAAAZING i understand every th after i wasn't U help me rly thanxz alot ^^

[alrightythenable]

in figure 7-12. wouldnt the sucrose (alpha-D-glucopyranoside) be alpha and not beta because it's flipped?

[astuteification]

Would you please clear out the flag pole concept, I am completely confused!

[Dorenimenimynimo]

Hi i love your videos! I think you're great! I did notice one mistake.... Lactose is made up of 2 Beta sugar forms. You named the second sugar alpha because you used the wrong carbon to reference its hydroxyl group to the "flag pole". If you had looked at the anomeric carbon/ carbon 1, you would have seen that the hydroxyl group is on the same side as the "flag pole", making the monosaccharide a Beta. Your technique is good, the book doesnt teach it this way.

thought the addition of sugar to hemoglobin was called glycation (opposed to glycosylation which synthesized by enzyme activity)

[DarthHater100]

@TheSinghp03 I was just going to write the same thing. The correct term is glycation. Glycosylation is enzyme mediated, where as glycation is not. For instance, glycosylation is facilitated by an enzyme in protein synthesis during post-translational modifications.

Alpha beta. Im confused. Must be an seldom error here?

@Moshpitssser alpha, OH group points down, Beta, OH group points up.
