Invertase mammalian

Bierry found that mammalian invertase is without action on raffinose and stachyose.37 Clarke and associates also obtained negative results, with both melibiose and raffinose.48... 

The glucose mimic, desoxynojirimycin (38) (fvomMorus, mulberry, Moraceae), inhibits a-glucosidases in the manuna-lian gut. A mannose analog, desoxymannojirimycin (39), inhibits mannosidases. Another alkaloid from Derris (Fabaceae) inhibits the action of invertase but does not prevent hydrolysis of this disaccharide in the mammalian gut. In artificial diets with Locusta migratoria, 0.001% of DMDP in the... 

Sucrase (also called saccharase and invertase) hydrolyzes sucrose. In contrast to the abundant information available on the yeast invertase, little is known of the mammalian sucrases. The significance of invertase and lactase in absorption is illustrated by inborn errors of metabolism in which these two enzymes are absent in the intestinal secretion. (The fact that lactase deficiency does not interfere with growth indicates that the galactose needed for biosynthesis of brain lipids or lens proteins can be synthesized endogenously in amounts sufficient to fulfill the metabolic requirements.) In that case, there is an intolerance to lactose or sucrose with no increase in blood glucose levels or without an increase in the levels of disaccharides...
