Pharmaceutical Biochemistry explores the biochemical processes underlying health, disease, and the action of drugs at the molecular level. It focuses on understanding biomolecules (carbohydrates, proteins, lipids, and nucleic acids), enzymes, and metabolic pathways to identify targets for drug design and therapy. This field examines drug metabolism, mechanisms of action, and the biochemical basis of diseases, linking them to therapeutic interventions. It also integrates clinical biochemistry to analyze biomarkers and monitor drug efficacy. With advancements in biotechnology, pharmaceutical biochemistry contributes to the development of biologics such as monoclonal antibodies, vaccines, and personalized medicines, bridging science and healthcare to improve treatment outcomes.
