Sketchy Medical Biochemistry Apr 2026
Biochem is 50% vitamins (B1, B2, B3, B6, Folate, B12). Sketchy embeds the vitamin as a "tool" or "weapon" in the scene. You stop asking "What does B1 do?" and start seeing the tire swinging in the scene whenever you think of decarboxylation reactions. The Critiques: Where the Metaphor Gets Strained 1. The "Crowded Canvas" Problem Microbiology scenes usually have 5-10 symbols. A biochem scene (e.g., the Urea Cycle or Glycogen Storage Diseases) might have 30-40 symbols crammed into a single image. The cognitive load shifts from "easy recall" to "Where is Waldo with enzymes." Students often report needing to pause the video every 10 seconds to parse the scene.
This is where Sketchy Biochem shines brightest. Remembering that Maple Syrup Urine Disease is caused by a defect in the E1 subunit of Branched-Chain Alpha-Ketoacid Dehydrogenase (requiring Thiamine and Lipoic acid) is brutal. In Sketchy, a lumberjack (maple syrup) is fighting a bear with a broken hockey stick (E1) while wearing a tire (Thiamine) and a lip (Lipoic acid). Suddenly, the esoteric becomes visual slapstick.

If you try to watch Sketchy Biochem before understanding the basic pathway, you will drown. The sketches are mnemonics for review , not primary teaching tools. A student who doesn't know what Glucokinase does will be confused by a drawing of a gluttonous kangaroo. You must read First Aid or watch Boards & Beyond first. Biochem is 50% vitamins (B1, B2, B3, B6, Folate, B12)
Learn the pathway logically from a textbook or video lecture. Then, watch the Sketchy to burn the disease associations and vitamin cofactors into your visual cortex. If you do that, you will never confuse Biotin with B6 again. And for the biochem-weary medical student, that peace of mind is worth the price. The Critiques: Where the Metaphor Gets Strained 1
Sketchy Biochem attempts to solve this by applying the same "Memory Palace" technique to metabolic pathways. Instead of a generic diagram of the mitochondria, they build a visual universe—docks, factories, construction sites, and jungles—where every character and prop represents an enzyme, vitamin, or disease. 1. The "Big Picture" Integration Traditional biochem teaching isolates pathways (Glycolysis, then TCA, then ETC). Sketchy links them. In their universe, the "Glycolysis" ship docks at the "Pyruvate Dehydrogenase" pier, which feeds into the "Citric Acid Cycle" factory. This visual continuity helps students realize that metabolism is a loop, not a list.
The short answer is yes. The long answer is more nuanced. Medical biochemistry is often the silent killer of Step 1 scores. Unlike micro (pure memorization of bugs and drugs) or pharm (receptors and pathways), biochem requires a mastery of dynamic flux . You don't just need to know that Lysine is ketogenic; you need to know what happens when Methylmalonyl-CoA mutase breaks.
