Where is maltase lactase and sucrase produced?
Where is maltase lactase and sucrase produced?
Clinical biochemistry of the gastrointestinal tract The main disaccharidases are maltase, sucrase-isomaltase and lactase (see Fig. 12.1). These enzymes are synthesized on the endoplasmic reticulum, transported to the Golgi apparatus and then to the brush border.
What is the name given to sucrase maltase and lactase?
Brush Border Hydrolases Generate Monosaccharides Polysaccharides and disaccharides must be digested to monosaccharides prior to absorption and the key players in these processes are the brush border hydrolases, which include maltase, lactase and sucrase.
Are sucrase and lactase enzymes?
Lactase-phlorizin hydrolase (LPH) and sucrase-isomaltase (SI) are intestinal microvillus membrane hydrolases that play important roles in carbohydrate digestion. These enzymes display characteristic patterns of expression during postnatal development.
What is sucrase and maltase?
Among them, maltase is the major enzyme responsible for the digestion and absorption of dietary starch, whereas sucrase can hydrolyze sucrose [9]. Maltase is a membrane-bound enzyme that binds to microvilli on intestinal enterocytes.
Where is sucrase produced?
the small intestine
Sucrase is secreted by the tips of the villi of the epithelium in the small intestine.
What are the 4 enzymes in the small intestine?
Small Intestinal Brush Border Enzymes
- Maltase-Glucoamylase and Sucrase-Isomaltase. Dietary starch is digested by α-amylase present in pancreatic secretions and, in many species, saliva.
- Lactase.
- Peptidases.
- Lipases.

Where is maltase made?
Small intestine
Where enzymes are produced
| Enzyme | Substrate | Where produced |
|---|---|---|
| Protease | Protein | Stomach, pancreas |
| Lipase | Lipids (fats and oils) | Pancreas |
| Pancreatic amylase | Starch | Pancreas |
| Maltase | Maltose | Small intestine |
What does the sucrase do?
The sucrase component of the enzyme is responsible for the digestion of sucrose into glucose and fructose, and also for the digestion of maltose into glucose.
What does the enzyme sucrase break down?
This enzyme is found in the small intestine and is responsible for breaking down sucrose and maltose into their simple sugar components. These simple sugars are then absorbed by the small intestine.
What is the function of lactase?
Normal Function This enzyme helps to digest lactose, a sugar found in milk and other dairy products. Lactase is produced by cells that line the walls of the small intestine.
What is the role of sucrase?
