  2. Brush border - Wikipedia

    en.wikipedia.org/wiki/Brush_border

    Brush border cells are found mainly in the following organs: The small intestine tract: This is where absorption takes place. [2] [3] [4] The brush borders of the intestinal lining are the site of terminal carbohydrate digestions. The microvilli that constitute the brush border have enzymes for this final part of digestion anchored into their ...

  3. Disaccharidase - Wikipedia

    en.wikipedia.org/wiki/Disaccharidase

    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".

  4. Intestinal villus - Wikipedia

    en.wikipedia.org/wiki/Intestinal_villus

    Intestinal villi (sg.: villus) are small, finger-like projections that extend into the lumen of the small intestine.Each villus is approximately 0.5–1.6 mm in length (in humans), and has many microvilli projecting from the enterocytes of its epithelium which collectively form the striated or brush border.

  5. Enteropeptidase - Wikipedia

    en.wikipedia.org/wiki/Enteropeptidase

    [1] [2] Absence of enteropeptidase results in intestinal digestion impairment. [3] Enteropeptidase is a serine protease (EC 3.4.21.9) consisting of a disulfide-linked heavy-chain of 82-140 kDa that anchors enterokinase in the intestinal brush border membrane and a light-chain of 35–62 kDa that contains the catalytic subunit. [4]

  6. Trehalase - Wikipedia

    en.wikipedia.org/wiki/Trehalase

    Individuals with a defect in their intestinal trehalase have diarrhea when they eat foods with high trehalose content, such as mushrooms. [6] Trehalose hydrolysis by trehalase enzyme is an important physiological process for various organisms, such as fungal spore germination, insect flight, and the resumption of growth in resting cells.

  7. Sucrase-isomaltase - Wikipedia

    en.wikipedia.org/wiki/Sucrase-isomaltase

    Sucrase-isomaltase is a bifunctional glucosidase (sugar-digesting enzyme) located on the brush border of the small intestine, encoded by the human gene SI.It is a dual-function enzyme with two GH31 domains, one serving as the isomaltase, the other as a sucrose alpha-glucosidase.

  9. Gastrointestinal wall - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_wall

    The microvilli create a brush border that increases the area for absorption. In the ileum there are occasionally Peyer's patches in the lamina propria. Brunner's glands are found in the duodenum but not in other parts of the small intestine.
