Intestinal nutrient transporter

Intestinal nutrient transporters are a group of membrane proteins primarily located in the epithelial cells lining the small intestine that mediate the absorption of dietary nutrients—including glucose, amino acids, peptides, fatty acids, vitamins, and minerals—across the intestinal barrier into the bloodstream. Most transporters in this category are members of the solute carrier (SLC) family (e.g., SGLT1/SLC5A1 for glucose, PEPT1/SLC15A1 for peptides, various SLC6, SLC7, and SLC38 proteins for amino acids), utilizing secondary active transport (often sodium-dependent co-transport), facilitated diffusion, and, less commonly, primary active mechanisms for substrate movement[1][4][5][7][8]. Regulation of these transporters is adaptive, responding to dietary intake and physiological demands, and disruptions or pathogenic changes in their function underlie a spectrum of metabolic, gastrointestinal, and systemic diseases[4][5][9]. Note: The term "intestinal nutrient transporters" is not a single molecular entity but a functional class that includes many specific proteins. Structured data should be captured at the level of individual transporter names (e.g., "Sodium-glucose co-transporter 1" or "Peptide transporter 1") rather than the collective descriptive term. Therefore, this entry is categorized as is_incorrect: true for structure mapping purposes.
