Sketchy Medical Biochemistry 〈99% ORIGINAL〉

If you're tired of mixing up homocysteine vs. cystathionine, or forgetting which dehydrogenase needs riboflavin—. It’s not magic, but it’s the closest thing to a memory palace for pathways. Invest the 8–10 hours to watch all the biochem sketches early in M1, and you'll thank yourself during dedicated Step 1 prep when those "gimme" biochem questions become free points.

: In-depth coverage of carbohydrate, lipid, and amino acid metabolism, emphasizing clinical pathologies like diabetes or inborn errors of metabolism. Genetics and Molecular Biology sketchy medical biochemistry

Rather than isolated pathways, Sketchy offers a massive, interconnected world representing the entire metabolic state of the human body: Fed vs. Fasted. Invest the 8–10 hours to watch all the
