Enzymes are vital for digestion and nutrient absorption. They catalyze biochemical reactions that break down complex food molecules into simpler, absorbable forms. For instance, proteases digest proteins into amino acids, lipases break down fats into fatty acids, and amylases convert carbohydrates into simple sugars. This process is essential for the body to utilize nutrients effectively. Any disruption in enzyme activity can lead to malabsorption issues, impacting overall health and leading to nutrient deficiencies.
