Question
Bio chemistry question! 1. Draw (hand-drawn, Haworth format) structural example of a monosaccharide that is NOT a mutarotator. Explain him. Thie "guy" does not need to be "natural."2. Give a structural (hand-drawn, Haworth) example of a monosaccharide that is a mutarotator. Explain him and his name. 3. Draw the structure of beta-D-lactose, using Haworth Projection Format.

Ignore the water.4. Draw the structure of alpha-D-lactose, using chair-form format. Again, ignore the water.5. Consider a mutarotation issue. Write the complete reaction, illustrating the mutarotation, starting from the BETA epimer of lactose. (THIS IS A BIOCHEM LECTURE QUESTION; use Haworth Projections.)
Answers
Draw the Haworth structures for $\alpha$ - and $\beta$ -D-galactose.
No cluster fun. We will see what is the habit stop. Okay. It is a way of writing a structural formula to represent the site click structure of mona security. It's simple three dimensional perspective. No, the very first Dagenham or the structure is Alfa be the electro rose again it goes. And the second structure is A V. To be the electors. Now, if we see both the structure, you teams that both the structure are safe. But we will see on right side. Yeah. Here it is. And poet at he's up at origin. Down red as in peter de galaticos. The oil group is on this side. This is the difference between Alfa D galactose and vita viti electrode. And this structure, Yes, and Harvard structure of alpha and they are the the electors.
So for a, um, Diegel Actos gives the same, um, al Doric asset as Elga lacked owes. So this is the same if you rotated by 180 degrees. So this is the L. And this will be from the D. And we want to question be the other out of Texas is a D Sugar and Leslie for C. We have the chair and this is for B R for beta de blacktop. IRA knows
Okay, so let's look at our inside. And let's just say that this enzyme is undie and time. So if we look at the same time, we can see that blue color will be on, right? I mean, the left Sorry. The right is gonna be red color, and then the one pointing towards the bottom is gonna be green. So we need a substrate. That's gonna be the same confirmation and colors as the enzyme. And if we look at the substrates on the right, we have a D one in an L one and the L is a mirror image of the and it's also, uh, not super implausible. So indeed substrate. We have blue on the left, red on the right and green in the middle and in the mirror image. We have red on the left, blue on the right and green in the middle. Well, if you try to put the l one into the enzyme, you're not gonna be able to, because the blue and the red won't match up with the inside. Whereas if you put the d, it will definitely matchup. And it'll be a good matchup because it will cause the cattle last reaction
So the Howard structure of Alfa de Glucose looks like this. So we have carbon into oxygen bonded to carbon, carbon, carbon, carbon and oxygen. That's the ring We have C H 20 each and here we haven't o age group. Here we have another O H. Group, another O age group and another pro age group. So this is LPD glucose. No Veda d glucose has the same general structure as Alfa D glucose. So the ring is the same again has the C H 20 h up here. Both difference lies in this carbon here where in beta deep glucose, the O. H. Is facing a different direction. There's balls went though, age down here Been here, everyone here. So this is the main difference between the Alfa Pan Beta deep glucose is this So each group in the direction of it faces
