I want to study several carbohydrates that includes but not limited to the following molecules:
I know that for any carbohydrate, possible list of carbohydrates isomers are
- single chain (L and D isomer)
- $\alpha$ and $\beta$ pyranose or six member ring structures
- $\alpha$ and $\beta$ furanose or five member ring structures.
Now, for ring structures there are several rotamers, mainly gg, gt and tg (g=gauche, t=trans) and also there are several anomers but I am not sure about them. Is there anything I'm missing?
For accurate thorough computational study, I need to identify all the isomers. Is there any single book or document that can guide me to screen the full potential energy surface?
Thanks for your kind help.
