Biochemistry combines the molecular approach of chemistry with the breadth and diversity of biology. Very much a laboratory science, it explores, unravels and explains every aspect of the structure and function of all living things at the molecular level.

Biochemistry continues to advance our understanding of how cells are constructed, how they function and communicate with each other, how genetic information is stored, expressed and passed on to the next generation and how all of the cell's chemistry is co-ordinated and controlled.

Because it covers the spectrum of complexity from bacteria, yeasts and viruses to humans, and includes plants, Biochemistry underpins other life sciences such as , , and as well as being a foundation subject for all the .
