Catalase

Antioxidant enzyme converting hydrogen peroxide to water and oxygen to protect cells.

Definition

An antioxidant enzyme that decomposes hydrogen peroxide into water and oxygen. It completes the action of SOD and constitutes a major cell defense mechanism against oxidative stress.

How it works

Catalase is an enzyme primarily present in peroxisomes of cells, especially in the liver and red blood cells. It transforms hydrogen peroxide, a toxic byproduct of metabolism, into harmless molecules. This enzyme works in synergy with SOD to form a complete and effective antioxidant system. It depends on iron and sulfurous compounds for optimal functioning. Deficiency in catalase may increase the risk of infections and chronic inflammatory diseases.

Role

Breaks down hydrogen peroxide into harmless molecules to protect cellular integrity and support immune defense.

Examples

  • Lamb's liver
  • Eggs
  • Cheese
  • Garlic
  • Onion
  • Mushrooms

Recommendations

Incorporate foods containing bioavailable iron and sulfurous compounds into your daily diet. Lamb's liver and eggs are particularly rich in catalase. Combine them with vitamin C sources to improve iron absorption and enzymatic efficiency.

Key takeaway

Catalase complements your antioxidant defense: prioritize liver, eggs, and sulfurous foods to support it.
