How many stereoisomers are possible for cortisone acetate?

Thus, 26=64 stereoisomers.

What is the number of possible stereoisomers?

Three stereoisomers are possible: one pair of enantiomers (A and B) and an achiral molecule C, called a “meso compound.” A meso compound is an achiral molecule that nonetheless contains a stereogenic atom.

How many chiral centers are in cortisone?

There are 6 chiral centres in cortisone.

How many pairs of enantiomers are possible for cortisone acetate?

Five pairs of enantiomers are possible. Was this answer helpful?

How many stereocenters are in steroids?

The generic steroid structure drawn above has seven chiral stereocenters (carbons 5, 8, 9, 10, 13, 14 & 17), which means that it may have as many as 128 stereoisomers.

How many carbons are in cortisone?

17 carbon atoms
Steroid numbering system and nomenclature. All steroids are related to a characteristic molecular structure composed of 17 carbon atoms—arranged in four rings conventionally denoted by the letters A, B, C, and D—bonded to 28 hydrogen atoms.

How many pairs of enantiomers are possible?

There are two pairs of enantiomers. Any given molecule has its enantiomer; the two other molecules are its diastereomers.

How do you find the number of enantiomers?

1. If ‘n’ is even (here n is the number of chiral centres): Number of enantiomers=2n−1. Number of meso compounds=2n/2−1. Total number of optical isomers=2n−1+2n/2−1.
2. If ‘n’ is odd: Number of enantiomers=2n−1−2(n−1)/2. Number of meso compounds=2(n−1)/2. Total number of optical isomers=2n−1.

What is a stereoisomer example?

For example, a right-handed and a left-handed glove are mirror images of one another that cannot be superimposed. The same is true for the two mirror image houses we talked about earlier. There is no way to rotate them around so that they are the same object – they will always differ in three-dimensional space.

What is the structure of cortisone?

C21H28O5Cortisone / Formula

What does cortisone contain?

It is a 17alpha-hydroxy steroid, a 21-hydroxy steroid, an 11-oxo steroid, a 20-oxo steroid, a C21-steroid, a 3-oxo-Delta(4) steroid, a primary alpha-hydroxy ketone, a tertiary alpha-hydroxy ketone and a glucocorticoid. It derives from a hydride of a pregnane. Cortisone is a Corticosteroid.
