For the undergraduate level, with basic graduate level exploration.
How to use this guide
- Do chemistry first.
- Draw everything. Structures, reaction mechanisms, enzyme cycles, membranes, gene expression flows, metabolic pathways etc.
- Do problems, not just reading.
- Learn the lab bench. A genuine biochemistry education is incomplete without assays, gels, chromatography, cloning/PCR, spectroscopy, and data analysis.
- Read papers after you do the core. Learn how the field actually argues.
