Question

Quizplus · Accepted Answer

Fumarate is a prochiral molecule because it has a double bond and can be converted into a chiral molecule by addition of a group to one of the carbons of the double bond. In the active site of fumarase, the double bond can be attacked from only one side due to the orientation of the enzyme, making fumarate a prochiral molecule.

When Fumarate Is Positioned in the Active Site of Fumarase,the
