Is dissacharidase a brush border enzyme?

Answer 1

Brush border enzymes are enzymes produced by the microvilli in the small intestine, carrying out some of the final stages of enzymatic digestion. These enzymes are not released into the lumen and digestion can only occur if the chyme is in contact with the brush border. Intestinal churning of chyme ensures that they come into contact with the mucosa.

Answer 2

Brush border enzymes are digestive enzymes located in the membrane of the brush border (microvilli) on intestinal epithelial cells. The brush border greatly increases the surface area available for the absorption of digested food. The enzymes include: * aminopeptidases, which break down peptides into amino acids * maltase, which hydrolyses maltose into glucose * sucrase, which hydrolyses sucrose into glucose and fructose * lactase, which hydrolyses lactose into glucose and galactose The products of these enzymes are then absorbed into the blood.

Answer 3

Digestion of food, i.e. breaking down large food molecules into smaller molecules which can be absorbed through the gut wall

Answer 4

These enzymes are vital for the absorption of nutrients,and if they are not present or the intestinal wall is impaired, malabsorption and various other dysfunctions can occur.

Answer 5

Brush border enzymes (located in the microvilli) within the GIT (gastrointestinal tract)

are involved in the terminal process of the digestion of carbohydrates and proteins.

Answer 6

Yes. It is the enzyme, which is present in the brush border of the intestine.

Answer 7

Yes.
