-
(2012)The karyotype of fifteen Leucocoryne taxa was studied, assessing characteristics such as chromosome morphology and size, secondary constriction location, and asymmetry level. Two groups of Leucocoryne taxa were described ...
-
(Oxford University Press, 1981)Liolaemus monticola, Müller and Hellmich, is a highly variable, endemic montane species distributed along the temperate Andes in Chile. The subspecies (Müller and Hellmich) karyotypes established from their type localities ...

-
(1965)Apyrase from potato extracts has been purified 200-fold by two different procedures; both procedures furnish an apyrase which splits ATP faster than ADP. By using P32-labeled substrates, it was possible to demonstrate that ...
-
(2003)The kinetic mechanism of rat liver hexokinase D (‘ glucokinase’) was studied under non-co-operative conditions with 2- deoxyglucose as substrate, chosen to avoid uncertainties derived from the co-operativity observed ...
-
(1984)The number and nature of glucose-phosphorylating enzymes of rat intestinal mucosa were investigated by chromatographic, electrophoretic, and kinetic methods. Three fractions with glucose-phosphorylating activity were ...
-
Kinetics and mechanism of the reaction of a nitroxide radical (tempol) with a phenolic antioxidant (2003)In the absence of redox-active transition metal ions, the removal of Tempol by Trolox occurs by a simple bimolecular reaction that, most probably, involves a hydrogen transfer from phenol to nitroxide. The specific rate ...
