The definitions in my book are a little vague, and while I think I pieced together what they mean, I did want to double-check these assumptions! If they're right you can just tell me that, quick and easy, but if I got anything wrong I may need a little explanation, esp. on the second part...
1) Acetals and Ketals vs. Glycosides- From the way my book phrased it, it sounds like acetals and ketals are formed from an open-chain hemiacetal (which is not as common), while glycosides are basically the same process but formed from a cyclic hemiacetal. Is this right- is it that simple?
2) I'm confused on how mutarotation differs from isomerization reactions. While mutarotation seems to mostly deal with shifts between the alpha and beta forms, my book says that mutarotation can also lead to both pyranose and furanose ring structures, even if they're in small amounts. I thought that that would count as an isomerization- does it? (Specifically, I'm looking at glucose- would a glucofuranose be a different isomer than a glucopyranose? If so, why would this be mutarotation and not isomerization?)
Thank you!
