Suzuki, Y., Oishi, K., Nakano, H., and Nagayama, T. (1987). A strong correlation between the increase in number of praline residues and the rise in thermostability of five Bacillus oligo 1,6-glucosidases. Appl. Microbiol. Biotechnol., 26, 546-551. [Pg.266]

Enzymes produced by the villi are sucrase, which converts sucrose to glucose and fructose maltase, which breaks down maltose to two molecules of glucose lactase, which hydrolyses lactose to one molecule of glucose and one of galactose and oligo-1,6-glucosidase, which attacks the a-(1 6) links in limit dextrins. Aminopeptidases act on the peptide bond adjacent to the free amino group of simple peptides, whereas dipeptidases complete the breakdown of dipeptides to amino acids. [Pg.162]

Specific determination of D-glucose (65) in plant exfi acts requires high purity GOX, devoid of /6-glucosidase, to avoid interference by hydrolysis of oligo- and polysaccharides that may lead to glucose formation and produce H2O2 on autoxidation ". ... [Pg.633]

By competitively inhibiting the alpha-glucosidase enzymes in the mucosa cells of the small intestine these agents suppress the breakdown of di-, oligo-and polysaccharides into monosaccharides and thus decrease carbohydrate absorption. In this way postprandial elevations of blood glucose levels can be prevented or diminished. [Pg.395]

The intestinal oligo- and disaccharidases are fixed components of the cell membrane of the brush border region of the wall of the small intestine. These enzymes digest dietary carbohydrate to monosaccharides which are absorbed through the intestinal wall. They include sucrase, maltase, isomaltase, lactase, trehalase, and hetero-p-glucosidase. In the late 1970s, it was realized that inhibition of all or some of these activities could regulate the absorption of carbohydrate, and that these inhibitors could... [Pg.125]

The absorption of simple and complex carbohydrates from the intestine is mediated by a family of enzymes collectively named a-glucosidases which hydrolyze the oligo- or poly-saccharides to monosaccharides for transport into the blood stream. Inhibition of these enzymes is expected to delay the absorption of carbohydrates and reduce the postprandial glucose rise. [Pg.34]

Studies on the specificities of purified a-D-glycosyl hydrolases of about eight kinds of yeast are summarized in Table XI. The enzymes of Saccharomyces cerevisiae, namely, a-D-glucosidase and oligo-(1 — 6)-D-glucosidase (EC 3.2.1.10), have been examined the most thoroughly. [Pg.193]

Because of the delay in absorption of oligo- and di-saccharides resulting from its administration, a colic bacterial fermentation occurs, accounting for the frequent abdominal discomfort mentioned by the patients. These side effects should be lessened with the second-generation glucosidase inhibitors now being developed. [Pg.163]
