Chemical characterization of proteases extracted from wild thistle (Cynara cardunculus)
(1990)
Three protease fractions were obtained by purification of a thistle extract with ammonium sulfate. The optimum pH and temperature on the proteolytic activity of the crude extract was found to be 5·7 and 37°C, respectively. ...
Does digestion rate affect diet selection? A study in Octodon degus, a generalist herbivorous rodent
(Springer Verlag, 1998)
Dietary chemistry and an animal digestive physiology should be considered in any explanation of behavioral patterns of food use, as both influence dietary preference. In the degu Octodon degus (Molina, 1782), a generalist ...
Endogenous and food-derived polyamines: determination by electrochemical sensing
(2018-09-01)
Polyamines (PAs) are involved in a variety of fundamental physio-pathologic processes. The concentration of these polycations in organs and tissues depends on their endogenous production and oxidation rates, and on their ...
Test of the adaptive modulation hypothesis in rodents: Dietary flexibility and enzyme plasticity
(1999)
The phenotypic response of digestive enzymes was assessed in two species of rodents with different foods habits. Species were Phyllotis darwini (omnivorous) and Octodon degus (herbivorous). The activity of sucrase, maltase ...
