"The Pyruvate Dehydrogenase sketch is a work of art. When I saw that question on Step 1 about 'Arsenic vs. Thiamine,' I saw the cartoon in my head. That's worth the price alone." –
Complex concepts like DNA replication and translation are simplified into mechanical analogies. 3. High-Yield Clinical Hooks sketchy medical biochemistry
: Visual mnemonics for Hurler, Hunter, Gaucher, and Fabry diseases. How to Use Sketchy Biochemistry Effectively "The Pyruvate Dehydrogenase sketch is a work of art
The Urea cycle is often a tangled mess of ornithine, citrulline, and argininosuccinate. Sketchy turns this into a "Disneyland ride" for nitrogen waste. Similarly, the horrors of Maple Syrup Urine Disease (MSUD), Phenylketonuria (PKU), and Alkaptonuria are distinguished not by confusing enzyme names, but by distinctly colored and shaped "mutant creatures" in the sketch. That's worth the price alone
This draft is written for a medical student or resident who wants to understand why a visual, story-based method works for this notoriously difficult subject, and how to use it effectively.
In the Sketchy universe, glycolysis happens in a gym. Here is how the mnemonic works:
Now, picture the Sketchy scene (often a "zoo" or "museum" for storage diseases). Each disease is a different animal or exhibit. "Fabry's" might be a fabric store with a broken "alpha" sign. The visual link between "Fabry" and "Angiokeratomas" becomes unbreakable.
