                                According to the National Institutes of Health, hundreds of transporters have been identified in the human genome. But what are nutrient transporters? Simply put, they are a diverse family of membrane proteins essential for facilitating the controlled movement of vital substances, from simple sugars and amino acids to vitamins and minerals, across cellular membranes.
