| dc.description.abstract | Interacción de DL-histidina, DL-treonina y DL-valina con ferrocianuros de platino y tungsteno. La interacción de adsorción de DL-histidina, DL-treonina y DL-valina en ferrocianuros de platino y tungsteno se estudió en un rango de pH de 1,0 a 10,0 y a temperatura ambiente (30 ± 1°C). El progreso de la interacción se siguió espectrofotométricamente midiendo la absorbancia de las soluciones de aminoácidos en su correspondiente λmax. A pH neutro, se encontró que la DL-valina y la DL-histidina mostraban una adsorción máxima y mínima, respectivamente, en ambos ferrocianuros metálicos estudiados. El tipo de adsorción de Langmuir se sigue en el rango de concentración de 10-3 a 10-4 M de soluciones de DL-histidina, DL-treonina y DL-valina. Los estudios actuales sugieren la importancia de los ferrocianuros de doble metal en la estabilización de biomoléculas de la degradación en la Tierra primitiva. | en |
| dc.description.abstract | Interaction of DL-histidine, DL-threonine and DL-valine with platinum and tungsten ferrocyanides.Adsorptive interaction of DL-histidine, DL-threonine, and DL-valine on platinum and tungsten ferrocyanides were studied at pH range 1.0 - 10.0 and room temperature (30± 1°C). The progress of interaction was followed spectrophotometrically by measuring the absorbance of amino acids solutions at their corresponding λmax. At neutral pH DL-valine and DL-histidine was found to show maximum and minimum adsorption, respectively on both metal ferrocyanides studied. The Langmuir type of adsorption is followed in the concentration range 10-3 to 10-4 M of DL-histidine, DL-threonine, and DL-valine solutions. Present studies suggest the importance of double metal ferrocyanides in the stabilization of biomolecules from degradation on primitive Earth. | en |
