WebThe aldopentoses have an aldehyde functional group at position 1. The ketopentoses have a ketone functional group in position 2 or 3. As the aldopentoses have three chiral centers, eight (2 3) enantiomers (see Section 7.2.1 and Fig. 7.8A and B) are possible, including d - and l-riboses, arabinoses, xyloses and WebWhen α-d-glucose dissolves in water, the optical rotation of the solution slowly changes from the initial value of + 112.2° to an equilibrium value of + 54°.If β-d-glucose dissolves in … an editable online encyclopedia WebView Homework Help - In-class-problem-set1_Solutions.pdf from CHEM 048 at Swarthmore College.
