Biochemistry is a multidisciplinary field that combines the areas of biology and chemistry. It may also involve disciplines such as physics, math, computing, genetics, and physiology.
Biochemists often work in interdisciplinary teams with physiologists, pharmacologists, plant biologists, microbiologists, chemists, agronomists, and other professionals.
In general, biochemists study the chemistry of biological molecules to better understand events and processes such as how:
- Living cells reproduce, acquire energy, grow, and develop
- Enzymes function
- Genes are regulated
- Organisms adapt to stresses and disease
Biochemists may specialize in areas such as:
- The chemistry of cellular processes such as metabolism, growth, and aging
- The neurochemistry of the brain
- Proteins, including enzymes, DNA, RNA, and other structures
- The 3D structure of biological macromolecules
- The molecular basis of how the immune system functions
- Mutations in organisms that lead to cancer and other diseases
- The way cells store and express genetic information
- How genetic variations affect responses to drugs
- Genetic engineering
- Biochemical diagnostic tests
- Recombinant DNA technology to produce pharmaceutically and industrially useful proteins
- Environmental analysis of soil and water quality and the interdisciplinary study of human impacts on the environment
- Food testing and quality assurance
- The development of new foods, food additives, health, or medicinal products
- Nanotechnology and the use of molecular machines and enzymes from cells for industrial applications
- The use of DNA fingerprinting techniques for forensic investigations
- RNA technologies, including vaccines
