Question

major nutrients absorbed in the small intestine?

Answer 1

Almost all the major nutrients are absorbed in the small intestine. By the time food reaches the small intestine, the process of digestion would have broken down complex molecules into monomers or simpler forms, which are then absorbed in the small intestine. These nutrients include:

• Carbohydrates after digestion of polysaccharide into monosaccharides.
• Proteins after digestion into small peptides and amino acids
• Fat after digestion into monoglyceride and free fatty acids
• Water, electrolytes and micronutrients are also absorbed in small intestine.
