2009-04-01

Resumen en español Se estudian los isómeros cis y trans del glicinato de cobre, como parte de un proyecto que pretende elaborar un suplemento nutricional con oligoelementos esenciales, considerando los factores que afectan la disolución y por lo tanto, la biodisponibilidad de los complejos. Con el fin de encontrar, en una etapa temprana de la formulación, una relación entre el proceso de disolución y algún parámetro de medida independiente del tamaño de partícula, se evalúan los d (mas) escriptores: circularidad, diámetro de feret, área, perímetro y dimensión fractal. Los que menor variación presentan son: circularidad y dimensión fractal, esta última puede relacionarse con el proceso de disolución calculando 2 propiedades relacionadas: la dimensión fractal superficial y la dimensión fractal reactiva. Este trabajo demuestra que en los complejos de glicinato de cobre a mayor tamaño de partícula la velocidad de disolución es mayor si existen grietas en la superficie, lo que se evidencia en una dimensión fractal reactiva mayor que .una dimensión fractal superficial. Isomers cis and trans of copper glycinate, as part of a project trying to make a nutritional supplement using essential oligoelements , considering the factors affecting dissolution, and thus, complexes bioavailability. During an early stage of formula, to find a relationship between dissolution process and some measurement parameter regardless of particle size, we must to evaluate following descriptors: circulation rate, feret diameter, area, perimeter, and fractal dimension. Those of a lower variation are: circulation rate and fractal dimension, this latter may be linked with dissolution process calculating two related properties: superficial and reactive fractal dimensions. This paper showed that in copper glycinate complexes, when the particle has a greater dimension, dissolution speed is greater too if there are superficial cracks, evident in a reactive fractal dimension greater than a superficial one.
