Biochemistry is the branch of science that explores the fundamental chemical processes within living organisms. Biochemistry considers molecular-level processes across a range of disciplines including genetics, microbiology, forensics, and medicine. Because of this breadth, biochemistry is hugely important and advances in this field over the past 100 years have been staggering. It's an exciting time to be part of this fascinating area of study.
At Essex, we specialise in structure-function relationships of biomolecules which offers insight into the interactions that occur in the complex cellular pathways that control vision and cell death. We also use computational approaches and bioinformatics to complement our research. On our BSc Biochemistry you study areas including:
molecular enzymology
neurodegeneration
structural biology
bioenergetics
In our large and friendly School of Life Sciences, you learn through a combination of lectures, seminars and practical lab sessions, giving you the opportunity to ask questions and develop skills by doing experiments at the laboratory bench.
You gain a solid grounding across a range of related topics, with the chance to contribute to real-world research projects in your final year of study.
We are ranked 2nd in the UK for biosciences (The Mail University Guide 2025) and 7th for biology (non-specific) for overall positivity score (National Student Survey 2024, English broad-discipline higher education institutions).
Our teaching is underpinned by research: new ideas and theories are tested in the classroom.
We insist on small-group tutorial teaching to complement your formal lectures.
Study abroad
Your education extends beyond the university campus. We support you in expanding your education through offering the opportunity to spend a year or a term studying abroad at one of our partner universities. The four-year version of our degree allows you to spend the third year abroad or employed on a placement abroad, while otherwise remaining identical to the three-year course.
Studying abroad allows you to experience other cultures and languages, to broaden your degree socially and academically, and to demonstrate to employers that you are mature, adaptable, and organised.
If you spend a full year abroad you'll only pay 15% of your usual tuition fee to Essex for that year. You won't pay any tuition fees to your host university.
Placement year
Alternatively, you can spend your third year on a placement year with an external organisation. This is usually focussed around your course, and enables you to learn about a particular sector, company or job role, apply your academic knowledge in a practical working environment, and receive inspiration for future career pathways.
Organisations our students have recently been placed with include GlaxoSmithKline (GSK), Proctor & Gamble (P&G), AquaTerra, AstraZeneca, Genzyme, Reckitt Benckiser, Thermo Fisher, and Isogenica.
If you complete a placement year you'll only pay 20% of your usual tuition fee to Essex for that year.

Teaching and learning will be through a mixture of lectures, classes, practicals and tutorials, with an emphasis on developing the key transferable skills needed for a career in biosciences.
The building blocks of life, plants and animals depend on the actions of individual cells. Investigate the biochemical characteristics of the small molecules and large macromolecules that allow cells to function. You examine the origins of life, cell structure and function, energy transductions, synthesis of molecules, and the eukaryotic cell cycle.
Microbes are essential for life, playing a vital role in connecting the health of humans, animals, and ecosystems. They aid in digestion, provide essential vitamins, and contribute significantly to our overall health and well-being. Marine microbes, for instance, produce approximately one-third of the oxygen we breathe. Additionally, microbes are indispensable for achieving the United Nations' Sustainable Development Goals, as they clean up pollutants and synthesize valuable products like antibiotics. However, not all microbes are beneficial - some cause devastating diseases. Despite significant advances in treatment and prevention, the incidence of infectious diseases continues to rise. In this module, you will explore the vast diversity and evolution of mostly beneficial microbes, alongside the pathogenicity of harmful ones. You will investigate how different viruses and bacteria invade, interact with, and replicate within their hosts. Through two practical sessions in our state-of-the-art teaching laboratory, you will study a food poisoning outbreak and will gain hands-on experience in growing, observing, purifying, counting, and even killing microbes. These sessions will equip you with highly sought-after skills, including aseptic technique, serial dilution, and data analysis.

Molecular biology is central to our knowledge of how biology "works" at a molecular level. This module explores the breadth of processes involved in the regulation of gene expression and the proteins that are made. You also discover the ever-expanding range of molecular biology techniques, including PCR, cloning and mutagenesis, and how these are applied to investigate and treat disease.
The study of cells is at the centre of modern biology. Learn how cellular components determine cell structure and function, how cells communicate and how signaling pathways regulate cell fate. You also explore the regulation of the cell cycle and cell death and learn about changes that occur in cells that have become cancerous. A solid understanding of cell biology opens doors to more specialist topics, such as plant biotechnology and cancer biology.
Assess the importance of zinc, copper and iron in biological systems and review how they are kept in stable equilibrium. Explore the structure and functions of proteins and enzymes that contain metal cofactors and discuss the diseases and possible treatments associated with both metal deficiency and overload.
Bioinformatics have become an indispensable skill for the next generation of biochemists and biologists in order to retrieve, analyse and interpret data. You will learn how to access, search and extract data from publicly available protein databases, and analyse and display results using appropriate software.
We are in the age of genomics and scientists have devised new technologies that can generate whole genome sequences in days which would once have taken years to achieve. Learn the high-throughput techniques of next-generation sequencing used to study genomes, the proteome and the interactome. Investigate how nucleotide sequences are analysed, applying the analytical tools used by research scientists and understand how new genes are discovered and their functions revealed. You also discover how our knowledge of gene structure is being applied in the emerging field of synthetic biology to create new organisms and modify existing ones by gene editing.
Understanding the shape, structure and folding of proteins can provide the basis for drug targeting in disease processes and enable us to develop a better understanding of specific biological pathways. This module takes a look at particular macromolecular assemblies using the most up-to-date structural biological techniques with a particular emphasis on x-ray crystallography.
This module aims to prepare you for carrying out an individual scientific investigation on a topic relating to your degree. Develop skills to identify a suitable question and then design an experimental approach to obtain data addressing this question. The assessment focuses on your analysis and presentation of these data in a suitable scientific paper format report, on the research, understanding and critical writing about the scientific literature relating to your project. Your oral project presentation skills and response to questions, the planning and management of your project work, your progress reflection and your employability skills will also be evaluated.
This module has been designed to enable students to integrate their subject knowledge with an understanding of sustainable development, acquiring the skills and competencies essential for addressing the urgent sustainability challenges of the 21st century.
Building upon knowledge gained in previous years, you discuss the mathematical and structural models used to gauge enzyme activity, the mechanisms of allostery and the experimental basis on which the various models of allostery may be distinguished. You also explore the mechanism of action of the dehydrogenases and the steady state mechanisms of multi-site enzymes.
Biomembranes are of fundamental importance in determining the organisation and functioning of living cells. Biophysical and biochemical methods to study membranes will be discussed alongside the specific roles of membranes in the signal transduction, ion and solute transport and energy storage in cells.
Energy generation and transformation by membranes is an essential feature of all cells: membrane electron transport processes will be discussed (with particular attention being given to respiratory and photosynthetic processes), together with the chemiosmotic theory for ATP synthesis by membranes. A bottom up approach building from basic thermodynamics to observed macroscopic effects and biological function is taken. Particular emphasis is placed on the quantitative description of chemical free energy changes and electron transfer reactions allowing students to analyse and interpret biophysical data in the context of actual experiments.
