Transport of Drugs & Nutrients

Above is a transmembrane protein that takes up, into your intestinal cells, orally consumed peptide nutrients and drugs. Its lumen-face (shown above) opens and binds peptide or drug, then closes, while its cytoplasmic face (opposite end from the above) opens to release its cargo into the intestinal cell, which passes it on into the blood circulation.
