Biocatalysts, such as enzymes and whole cells, play a significant role in sustainable chemistry. They are highly specific, efficient, and operate under mild conditions (e.g., ambient temperature and pressure, and aqueous solutions). Enzymatic processes are used in various industries including pharmaceuticals, agriculture, and food processing. The use of renewable feedstocks and the ability to catalyze reactions with high selectivity and minimal by-products make biocatalysts a cornerstone of green chemistry.
