So sugars that consists of two individual monomers. So three important types of disaccharidases that you should be familiar with is Maltase which breaks down maltose. We have Succeeds which breaks down sucrose and we have Lactase, which breaks down lactose. Now peptidases are basically those proteolytic enzymes that break down our peptides. And a specific type of peptidase that is found at the brush border is Dipeptidase. Dipeptidase is a proteolytic enzyme that breaks the peptide bonds in a peptide that only consists of two amino acids.
