Intestinal juice, secreted by glands in the walls of the small intestine, contains enzymes that further break down proteins into amino acids, complex carbohydrates into glucose, and fats into fatty acids and glycerol.
Intestinal juice in the small intestine plays a vital role in digestion and absorption. It contains enzymes like peptidases, which further break down peptides into amino acids, completing protein digestion. Additionally, intestinal juice contains maltase, sucrase, and lactase, enzymes that hydrolyze disaccharides into simple sugars (glucose, fructose, and galactose). These enzymes aid in the digestion of carbohydrates. Intestinal juice also contributes mucus, providing lubrication and protection to the intestinal lining. Together with pancreatic and bile secretions, intestinal juice facilitates the final stages of digestion and maximizes nutrient absorption in the small intestine, ensuring the extraction of essential components for energy and growth.
