WebFeb 13, 2024 · Diastereomers are stereoisomers with two or more chiral centers that are not enantiomers. Diastereomers have different physical properties (melting points, boiling points, and densities). Depending on the reaction mechanism, diastereomers can produce different stereochemical products. Introduction 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 ...
