The Chemical Breakdown Champions
Every day, your digestive system performs an incredible feat of chemistry. The large molecules in your food - proteins, carbohydrates, and fats - are far too big to be absorbed into your bloodstream. Enter digestive enzymes: biological catalysts that break down these complex molecules into smaller, absorbable units. Without these molecular scissors working at precisely the right conditions, we couldn't extract nutrients from our food.
