WebIn chiral reactions, bonds with chiral centers remain intact: The configurations of one compound can be compared to those of another using these reactions. If a bond to a … WebMany biochemical reactions convert an achiral reactant to a single enantiomer of a chiral product Reactions in living systems are catalyzed by enzymes, which are enantiomerically homogeneous. The enzyme (catalyst) is part of the reacting system, so such reactions don't violate the generalization that "Optically inactive starting materials can't ...
