SGLT1, or Sodium-Glucose Transporter 1, is a protein found in the cells of the small intestine. It plays a crucial role in the absorption of glucose and galactose from the food we eat. By using sodium ions to help transport these sugars across the cell membrane, SGLT1 ensures that our bodies can effectively utilize carbohydrates for energy. In addition to its role in digestion, SGLT1 is also important in maintaining blood sugar levels. It helps regulate how much glucose enters the bloodstream after meals. Dysfunction in SGLT1 can lead to conditions such as glucose-galactose malabsorption, affecting nutrient absorption and overall health.
