Chemistry Question on Biomolecules
Natural glucose is termed D-glucose because :
A
−OH on the second carbon is on the right side in Fischer projection
B
−OH on the sixth carbon is on the right side in Fischer projection
C
−OH on the fifth carbon is on the right side in Fischer projection
D
It is dextrorotatory
Answer
−OH on the fifth carbon is on the right side in Fischer projection
Explanation
Solution
Fischer gave the prefix "D" to compounds whose bottom chiral has its OH to the right. So natural glucose is called D-glucose or dextrose. Structure of D-Glucose:
