Disaccharidases are glycoside hydrolases, enzymes that break down certain types of sugars called disaccharides into simpler sugars called monosaccharides. In the human body, disaccharidases are made mostly in an area of the small intestine's wall called the brush border, making them members of the group of "brush border enzymes".
Examples of disaccharidases
- Lactase (breaks down lactose into glucose and galactose)
- Maltase (breaks down maltose into 2 glucoses)
- Sucrase (breaks down sucrose into glucose and fructose)
- Trehalase (breaks down trehalose into 2 glucoses)
