Thee Role of Biochemical Catalysts in Green Chemistry

Te high selectivy of enzymes is a critical providage. Traditional catalogs often produce a mixture of isomers or side products, requiring g costly cleanification steps.

Thi precision is vital for industries like appeeuticals, where enantiomeric purity can determinae a drug 's efficacy and safety. Moreover, enzymes are biodegrade redived frenved frendeablebble.

Biochemical catalogs fall intro several classes based on type of reaction they catalyze.
