They're simply too large. So what happens is on the membrane of our anterocytes, the cells in our small test, and we have specialized types of digestive enzymes that can break down disaccharides into their individual monomers. Now, the membrane of our anterocy is known as a Brush Water because it consists of microvilli. So this is a single cell found in the small intestine. This is known as an anteraside. And on the apical side of the cell, apical simply means it faces the lumen cavity of the small intestine.
