Biochemistry can seem daunting, but in the MRCOG Part 1 exam it is tested in a focused, predictable way that rewards clear understanding.

Mapped to the MRCOG Part 1 syllabus, our revision notes cover carbohydrate, lipid and protein metabolism, enzymes and their regulation, steroid hormone synthesis, vitamins and trace elements, iron and haem metabolism, and acid-base balance. Each topic is linked to the clinical context of obstetrics and gynaecology, including the metabolic changes of pregnancy, maternal and fetal glucose handling, and the biochemical basis of conditions commonly seen in single best answer (SBA) questions.

Whether you're revisiting biochemistry for the first time since medical school or polishing key topics before the exam, these notes make the subject manageable and exam-focused. They're free to access and designed to work alongside your question practice.
