Q54 E_a.
Question
Ribose, an essential part of ribonucleic acid (RNA), has the following structure:
(a) How many chirality centers does ribose have? Identify them.
(b) How many stereoisomers of ribose are there?
(c) Draw the structure of the enantiomer of ribose.
(d) Draw the structure of a diastereomer of ribose.
Step-by-Step Solution
Verified(a) There are three chirality centers present in ribose and are shown below.
Ribose is an organic compound and is considered a simple sugar consisting of 5 carbon ring. An aldehyde group is present at the end of the open-chain of ribose, which is why it is known as aldopentose.
(a) The number of chirality centers in ribose is three and is shown in ribose by the “*” sign. All these three chiral centers have four different groups attached.
