How can I draw and identify the chiral centers of 5-deoxyribose?
Step 1. Draw ribose.
Step 2. Convert it to 5-deoxyribose
Remove the O atom from the OH group at C-5.
The CH₂OH group becomes a CH₃ group.
Step 3. Identify the chiral centres.
The atoms with four different groups are C-2, C-3, and C-4 (the ones with OH groups).
Note: The common form of deoxyribose is 2-deoxyribose.
