Modulación del metabolismo del glicerol en tejido adiposo.

Abstract

En el presente estudio hemos determinado la influencia de variaciones de glicerol y glucosa sobre la metabolización del propio glicerol por el tejido adiposo de rata incubado in vitro. Con esta finalidad hemos incubado trozos de epidídimo graso de ratas alimentadas en medio de Krebs-Ringer-bicarbonato conteniendo albúmina bovina purificada y glicerol-1-C14 • A distintos tiempos de incubación se han valorado las variaciones en la actividad específica del trazador, para llegar a expresar los datos en unidades de velocidad, en función del glicerol no radiactivo que sale al medio de incubación vía lipólisis y del que es remetabolizado por el propio tejido. Un aumento en la conc.entración de glicerol en el medio de incubación produce un aumento de las velocidades de síntesis de CO2 y glicerol de glicéridos a partir del mismo substrato. La glucosa produce un aumento de las velocidades de síntesis de CO2 y ácidos grasos a partir de glicerol, pero inhibe su conversión a glicerol de glicéridos. Los resultados se estudian en función de los efectos competitivos de la glucosa y el glicerol para la síntesis de ~-glicerofosfato y la necesidad de la glucosa para la lipogénesis a partir de glicerol en tejido adiposo, como fuente energética para la síntesis de ATP y de coenzimas reducidos para la síntesis de ácidos grasos.
