draw the structure of a diastereomer of deoxyribose
Carbohydrates Part 1 Monosaccharide Structure
The diagram on the right shows the 3-dimentional view of D-ribose (an aldopentose – a sugar containing 5 carbons and an aldehyde functional group) On the left |
On one “hand”, native DNA found in all living organisms consists exclusively of D-deoxyribose sugars (D-DNA) and forms right-handed helices.
On the other hand, its enantiomer, L-DNA, consists of L-deoxyribose sugars and forms left-handed helices.
What are the diastereomers of ribose?
Diastereomers are compounds that contain two or more chiral centres and are not mirror images of each other.
For example, the aldopentoses each contain three chiral centres.
Thus, D-ribose is a diastereomer of D-arabinose, D-xylose, and D-lyxose.
