MCAT Question A Day - 4/2/13 - Answer!
Glucose anomers differ only:
A. by their glycosidic linkages.
B. in their number of carbon atoms.
C. in their configuration about carbon-1.
D. in the number of chiral carbons.
The correct answer is (C). Aldoses and their glycosides have cyclic structures that can differ
in the configuration about C-1. The C-1—OH is on the right in the a anomer and on the left in
the b glucose anomer.
