is the study of enzymes—biological molecules that act as catalysts to accelerate chemical reactions in living organisms. It explores the structure, function, mechanism, and regulation of enzymes. Enzymes play a critical role in metabolism, DNA replication, signal transduction, and cellular processes.
Enzymology and enzyme kinetics have widespread applications and potential for the future:
- Medicine:
- Drug discovery and design (e.g., enzyme inhibitors for diseases like cancer or HIV).
- Diagnostic tools (e.g., enzyme-linked immunosorbent assays - ELISA).
- Personalized medicine using enzyme-based drug metabolism studies.
- Biotechnology:
- Development of enzyme-based industrial processes (e.g., detergents, food processing, and paper production).
- Production of biofuels through enzymatic degradation of biomass.
- Genetic engineering of enzymes for enhanced properties.
- Agriculture:
- Enzymes for improving soil health and crop productivity.
- Biocontrol using enzymes to protect plants from pests and pathogens.
- Environmental Science:
