Biochemists study the chemical and physical principles of living things, and of biological processes such as cell development, growth, and heredity at the molecular level. It is a lab-based science, studying components such as proteins, lipids and organelles, bringing together both chemistry and biology in order to understand and solve problems.

Biochemistry covers a broad spectrum of scientific disciplines. It includes genetics, microbiology, forensics, plant science and medicine. Some biochemists work in research, examining different genetics or drawing out maps of cell structures in various organisms. Biochemists also analyse the complex reactions of living organisms such as metabolism, reproduction and growth.

Typical qualificiations

A bachelor’s degree in biochemistry is the norm. A postgraduate qualification will see a typical biochemistry graduate specialise in a vast range of subjects such as medicine and pharmacology, microbiology, immunology, genetics, cell biology, agricultural science,environmental sciences, and nutrition to name but a few!

Alternative routes to a bachelor’s degree in this area may apply to students that have a PLC qualification in a related course or general science certification or diploma.
