WebAug 28, 2024 · Chirality/Stereochemistry Video Series: Video 5 R and S configurations are found by ranking substituents on a chiral carbon. This is relatively straight-forward when substituents contain 1-3 atoms. This gets more confusing when the substituents are long, complex, and contain many of the same atoms. WebStereochemistry is an important issue in any synthesis. This chapter illustrates two key points. ... Biochemical processes are catalyzed by enzymes that have multiple stereogenic centers, and are therefore chiral. Enzymes provide a chiral environment in which to form stereogenic centers. Thus, only one enantiomer forms from an enzyme-catalyzed ...
