Carbonyl

... that they are mirror images of each other. The reason for differences in α vs. β D-glucose is entirely different. It is because of the way the carbonyl carbon is bonded to the oxygen of the sixth carbon. I apologize for causing this needless confusion. I think I have one more question, Jonmoulton. ...

... form. When the aldehyde reacts intramolecularly to form a closed ring, the resulting ring will be in α or β form depending on which face the carbonyl carbon (C1) forms the ring-closing bond. However, free D-glucose is a mixture of α and β forms and they are dynamically interconverting though ...

... complex. To my knowledge, no one has done a calculation on which of the above-described pathways is more probable. [The reduction is from an acid carbonyl to an aldehyde carbonyl, a difficult, many-body problem, I think.] If I were to guess, I'd go for the "hydrogen tunneling" rather ...

They have hydroxyl groups and carbonyl groups... I'm guessing they are hydrophilic because glucose can dissolve in water (though it forms a ring structure)?
