And so this is what the g one ganglio side actually looks like. We have this lipid component inside the membrane and we also have these five sugars shown here, which are basically pointing towards the outside of that membrane they're found in the lumen of that small intestine. And so these five binding bee chains basically go on and bind onto this GM one ganglioside. And once they bind, an endocytosis process takes place in which the cell membrane basically invaginates and it engulfs this structure. And what happens is once that engulfing process takes place, this catalytic A chain is released into the cytoplasm. So once bound, the catalytic A chain moves into the epithelial cell of the small intestine v the process of endocytosis.
