[ES]: Se estudia la influencia de las 3 variedades más importantes de la grasa de la dieta (cantidad, calidad y composición) sobre la composición y distribución de ácidos grasos del tejido adiposo, utilizando ratas como animales de experimentación. Los resultados obtenidos a partir de 11 grupos de ratas permiten deducir las siguientes conclusiones: 1. - La composición de ácidos grasos de la grasa del tejido adiposo puede ser muy variable. Contenidos de grasa en la dieta superior al 12% originan un perfil de ácidos grasos en tejido adiposo muy similar al de la grasa ingerida. 2.- La alteración de la grasa de la dieta modifica la composición de ácidos grasos del tejido adiposo, debido a la menor cantidad de grasa absorbida. 3.- La distribución de los ácidos grasos en los triglicéridos del tejido adiposo es independiente de la de la grasa ingerida.
[EN]: In this paper the effect of the 3 most important variables (quantity, quality and composition) of dietary fat on the distribution and composition of fatty acids in rat adipose tissue, is studied. From the results obtained after feeding 11 groups of rats, the following conclusions stand out: 1 . - Fatty acid composition of rat adipose tissue is very variable. Nevertheless, when the percentage of fat in the diet is higher than 12%, the fatty acid composition of the adipose tissue is similar to that of the ingested fat. 2.- The level of alteration of the fat in the diet clearly modifies the fat composition In adipose tissue. This fact might be due to the lower digestibility. 3.- Fatty acid distribution in adipose tissue is independent of the distribution in the ingested fat.
