TLDR
All disaccharidase activities have been found to have the same distribution through the different sections of small intestine except for trehalose glucohydrolase activity which decreased distally more than the otherdisaccharides.About:

Plasma concentrations of total and free corticosterone during development in the rat.
TL;DR: The data suggest that the rise in free corticosterone that begins on day 14 acts as a cue for enzymic changes in both liver and intestine.

Lactase Deficiency: An Example of Dietary Evolution
TL;DR: It is hypothesized that prior to the domestication of animals and the development of dairying, the normal condition for all men was adult lactase deficiency, but that with the introduction of lactose into the adult diet in certain cultures, new selective pressures were created that favored the genotype for adult lact enzyme production.
Journal ArticleDOI
Development of the gastrointestinal tract.
TL;DR: This review uses the rat as a model system for a discussion of the functional development of the gastrointestinal tract and finds that the neonate has hydrolytic activities which are specific for, and largely restricted to, the components of maternal milk.

Dietary, Phylogenetic, and Ecological Correlates of Intestinal Sucrase and Maltase Activity in Birds
TL;DR: Intestinal sucrase and maltase activities were measured in three species of hummingbirds and 11 species of passerine birds from western Mexico and found that Hummingbirds and passerines differed in the relationship between maltase and suCrase activities.

The Determination of Enzyme Dissociation Constants
Hans Lineweaver,Dean Burk +1 more
TL;DR: On the basis of the assumed theory the rate of the observed reaction is directly proportional to the concentration of the enzyme-substrate compound, where (E:l = (ES).
