Complete Step 1 biochemistry content organized into eight major topics. Each module includes core topics, high‑yield subtopics, and clinical correlations. Follow the hierarchical links to master every concept.
DNA structure & replication, transcription, translation, gene regulation, mutations, and epigenetics. Foundational for understanding inheritance and molecular medicine.
Explore module →Cell cycle, apoptosis, signaling pathways, cytoskeleton, organelles. Essential for understanding cancer, immunology, and tissue homeostasis.
Explore module →Glycolysis, gluconeogenesis, TCA cycle, oxidative phosphorylation, pentose phosphate pathway. Core metabolic pathways with frequent Step 1 emphasis.
Explore module →Fatty acid oxidation & synthesis, ketogenesis, cholesterol metabolism, lipoproteins, eicosanoids. Key for cardiovascular disease and energy regulation.
Explore module →Amino acid catabolism, urea cycle, heme synthesis, one‑carbon metabolism, protein folding. Direct links to inborn errors of metabolism.
Explore module →Purine/pyrimidine synthesis & degradation, salvage pathways, nucleotide analogs. Critical for understanding chemotherapy and genetic disorders.
Explore module →Water‑soluble and fat‑soluble vitamins, trace minerals, and their biochemical roles. High‑yield for deficiency syndromes and enzyme function.
Explore module →Fed vs. fasting states, hormonal regulation (insulin, glucagon), tissue‑specific metabolism, metabolic syndrome. Integrates all pathways.
