My favourite module was the Biological Chemistry module in 2nd year. There was a part of that module on neurological diseases which covered Parkinson’s, Dementia, Huntington’s Disease and Depression. Learning about the pathways within the brain, how these are impacted by the diseases, and how modern therapeutics look to alter these pathways was very different to content covered in a ‘standard’ Chemistry degree and was a fascinating look into some diseases that we are still trying to fully understand.
