Molecules that have the same molecular formula and also have their atoms bonded in the same order, but these atoms are arranged differently in space.
1 of 9
What two types of stereoisomers are there?
E/Z isomers and optical isomers.
2 of 9
What is a chiral centre?
An atom which has four different groups of atoms attached to it.
3 of 9
What are enantiomers (optical isomers)?
Molecules which have a non super-imposable mirror images.
4 of 9
In what biological molecules is optical isomerism often found?
Amino Acids
5 of 9
What is the CORN rule?
When you note the direction of the sequence of COOH,R, NH2 in an enantiomer.
6 of 9
What is the L isomer?
The enantiomer which follows the CORN rule clockwise.
7 of 9
What is the D isomer?
The enantiomer which follows the CORN rule anticlockwise.
8 of 9
How do enantiomers differ?
Enantiomers behave differently in the presence of other chiral molecules. The body has many chiral molecules - enzymes, hormones etc, so enantiomers often smell, taste and work differently as medicines.
