Global and local analysis of the gas-phase acidity of haloacetic acids
(2000)
The relative gas-phase acidity of halosubstituted acetic acids CH2XCO2H, CHX2CO2H and CX3CO2H (X = F, CI, and Br) is analyzed in terms of global and local descriptors of reactivity. The model is based on the analysis of ...
Effects of inhibition gastric acid secretion on arterial acid-base status during digestion in the toad Bufo marinus
(Elsevier B.V., 2003-07-01)
Digestion affects acid-base status, because the net transfer of HCl from the blood to the stomach lumen leads to an increase in HCO3- levels in both extra- and intracellular compartments. The increase in plasma [HCO3-], ...

Methionine to cystine ratio in the total sulfur amino acid requirements and sulfur amino acid metabolism using labelled amino acid approach for broilers
(2018-11-22)
Background: Assuming that part of Methionine (Met) is converted into Cystine (Cys), but ignoring the rates with which such phenomenon occurs may lead to an excessive supply of Met in poultry diets. Such inconvenient could ...
