I have just studied the concept of cyclotron in carbohydrates. My reference book used Glucose as an example and began by saying we can find D-glucose or L-glucose:
Depending on what enantiomer we have, we will get opposite chair conformations at cyclisation:
After saying this, my book states that significant differences appear at cyclisation of these enantiomers, and there I just do not follow. The only difference I see is that one is the mirror image of the other. But visually, I see both structures identically equal.
Could someone explain to me what differences I should be observing in both chair conformations, and also, what consequences these have on the molecules' behaviors?
