Biochemist
Unravel the chemistry of life — investigate the molecular reactions inside cells, develop drugs, and advance our understanding of metabolism, disease, and nutrition.
Biochemists study the chemical processes and molecules that underlie all living systems — enzymes, proteins, DNA, carbohydrates, lipids, hormones, and the metabolic pathways that link them. In the medical context, biochemists contribute to drug discovery and development, clinical diagnostics (clinical biochemistry laboratory), nutritional science, toxicology, and disease research. In Sri Lanka, Biochemistry is taught as a BSc Special degree at the Universities of Peradeniya, Colombo, Kelaniya, and Ruhuna. Graduates work in hospital clinical biochemistry laboratories, pharmaceutical companies, food and beverage industry R&D, the Medical Research Institute (MRI), and academic research. Internationally, Biochemistry is a strong foundation for careers in pharmaceutical R&D, molecular medicine, clinical research, and biotechnology. A Biochemistry degree also provides an excellent pathway to graduate-entry medicine in some countries.
What a Biochemist does daily
- Investigate metabolic pathways — how cells produce energy, synthesise molecules, and break down nutrients
- Study enzyme kinetics and protein structure-function relationships
- Develop and validate biochemical assays for clinical diagnostics
- Perform clinical biochemistry tests — liver function, kidney function, lipid profiles, hormones, enzymes
- Research drug mechanisms — how pharmaceuticals interact with molecular targets
- Investigate the biochemical basis of diseases — diabetes, cardiovascular disease, cancer metabolism
- Contribute to food science — nutritional biochemistry, food safety, and product development
- Conduct toxicology studies — drug metabolism, environmental toxicants, forensic chemistry
Step-by-Step Career Roadmap
- Build Chemistry and Biology foundations with equal rigour — Biochemistry demands both at an advanced level
- Develop genuine fascination with molecules — how sugars, fats, proteins, and DNA are built and function
- Study basic metabolism — how food is broken down and used for energy
- Build strong Mathematics skills — biochemistry calculations require algebra, logarithms, and statistics
- Read popular science on molecular biology and chemistry — "The Vital Question" (Nick Lane), "Life Ascending" (Nick Lane)
- Chemistry experiments at home or school
- Biology Olympiad
- Science fair — biochemistry project
- Khan Academy Organic Chemistry intro
- Biochemistry requires Chemistry to be as strong as Biology — if Chemistry is a weak subject, this career will be very challenging
