The early work on intestinal lactase has been reviewed by Plimmer (1906) and Oppenheimer (1925). No uniformity of opinion was reached regarding the presence and dist,ribution of this enzyme in the intestinal mucosa or in intestinal juice. Without attempting to review these investigations again, it suffices to state that some authors found lactase in the small intestine of young animals. Others ...

The current requirements of industrial biocatalysis are related to economically beneficial and environmentally friendly processes. Such a strategy engages low-temperature reactions. presented approach is essential, especially in food processes, where temperature affects the quality nutritional value foodstuffs. subject study hydrolysis lactose with commercial lactase NOLA™ Fit 5500 (NOLA). comp...

In paediatric practice proper digestion of carbohydrates is of major importance for adequate growth and development and for prevention of intestinal complaints. Several carbohydrates can be considered in this respect: (a) lactose: the main carbohydrate in the nutrition of early life and also in later life for many white people; (b) starch: the main energy supplier in our food; (c) fructose: a c...

Trypanosoma cruzitrans-sialidase (TcTS), which catalyzes the transfer or hydrolysis of terminal sialic acid residues, is crucial to the development and proliferation of the T. cruzi parasite and thus has emerged as a potential drug target for the treatment of Chagas disease. We here probe the origin of the observed preference for the transfer reaction over hydrolysis where the substrate for TcT...
