Explanation / Answer

There are also assortments of enzymes embedded along the luminal surface of the villous projections of the epithelial cells (called Brush border) that line the intestine. Collectively, these enzymes are referred to as intestinal alpha-amylase enzymes and they complete the final digestion of carbohydrates in the small intestine. One of these includes Lactase which splits the bond between the galactose and glucose molecules in milk sugar. Another of these is a dual-purpose molecule that contains one subunit referred to as the Sucrase subunit that splits the bond between the glucose and fructose molecules in table sugar. The other component of this dual-purpose enzyme is referred to as the Alkaline component and possesses enzyme activity that breaks the 1-6 'branch-point' linkages in the -limit dextrans and the bonds between the glucose molecules of maltose and maltotriose molecules produced by the pancreatic and salivary -amylases. Lastly, maltase also helps to split the bonds between the glucose subunits in maltose and maltotriose molecules. When these enzymes are present in sufficient, functional quantities, they completely convert all absorbed complex polysaccharides and sucrose and lactose molecules (and other minor sugars) to the 3 absorbable glucose which are, listed alphabetically, 70, 30 and 100.
