Amino acids, enzymes, metabolism pathways, vitamins, neurotransmitters — the biochemistry content that appears most on the MCAT and USMLE Step 1.
Master all 20 amino acids by their chemical properties — not by rote memorization. Includes essential vs. non-essential, clinical deficiency diseases, and the metabolism connections tested most on the MCAT and USMLE.
Acetylcholine, dopamine, serotonin, GABA, glutamate — every major neurotransmitter system explained with synthesis, receptors, clinical pharmacology, and the drug mechanisms built on top of them.
Scurvy, pellagra, Wernicke-Korsakoff, rickets, megaloblastic anemia — every vitamin deficiency disease mapped to its function, cause, and treatment. The most clinically tested topic in all of biochemistry.
