Alcoholic Fermentation: From Sugar to Ethanol, the Complete Chemistry
Alcoholic fermentation has produced wine, beer, and bread for millennia. Behind the apparently simple transformation — sugar → alcohol + CO₂ — are ten chained enzymatic reactions with an elegant biochemical logic.
Capsaicin: the Chemistry Behind the Heat of Chili
Spiciness is not a flavor — it is a pain response. Capsaicin activates the same receptors that detect physical heat, tricking the brain into thinking the mouth is on fire. All because of one molecule.
Glucose vs Fructose: Two Isomers, Two Metabolic Destinies
They share the molecular formula C₆H₁₂O₆ and nearly the same sweetness, but their metabolic paths in the body are radically different. A single carbonyl position change has profound metabolic consequences.
