Questions in Carbohydrates

- In lecture, you mentioned that beta-1,4 glycosidic linkages are more stable than alpha-1,4 glycosidic linkages. I was just wondering why that is. There seems to be no difference between the two linkages other than the orientation of the hydrogen atom.(200969 views)
- Isn't an aldehyde group also called something else?(18845 views)
- If you did not know a linear structure was cellulose, how could you identify that it is mimicing a 3D rotation? What are the clues to know it is an alpha or beta?(20518 views)
- Several lectures ago we were discussing the breaking of disaccharides by the body and that it was as simple as an alpha linkage vs. a beta linkage to be able to digest Maltose vs. Cellobiose. Well I was wondering if it was the same concept for people who are lactose intolerant and if they are missing the ability to break the bond between glucose and galactose?(20334 views)
- Even though I know how to recognize the difference between alpha and beta glycosidic linkages (by H above or below the first carbon), I was wondering about the real reason why they're called Alpha and beta hydrogen. Can anyone tell me the real chemical reason or perhaps give me possible links that explain that matter?(18320 views)
- I was wondering if it is chemically right to add a pentose and a hexose sugar or any two sugars with different amount of carbons using glycosidic linkages? If so, would you name them the same way we have learned?(18145 views)
- In one of the lecture slides, there is a picture of alpha galactose and fructose, hypothetically if these two were mixed and they have different ring structures even though they are both hexose sugars could you bind them? If so, how would you name this linkage?(20891 views)
- I have a question about alpha and beta 1,4 glycosidic linkages. Can a polyssacharide have alternating alpha and beta linkages? For example, in the slide about the alpha and the beta Glucose molecules coming together to form Maltose, I understand that the bond that forms is an alpha 1,4 linkage. However, if another molecule was added on to the Beta glucose, the bond would be a 1,4 Beta linkage.(19541 views)
- Does cellulose act as energy storage and building structure in plant cells?(22719 views)
- Can you please explain the difference between branched and unbranched? What makes this property significant and how can you know which one is which with electron microscopy?(19214 views)
