Lopes, Paula Alexandra; Vicente, Luís; Rodrigues, V. O.; Santos, V. C.; Napoleão, Patrícia; Pavão, Maria Leonor; Nève, Jean; Viegas-Crespo, Ana MariaEl selenio (Se), el cobre (Cu) y el cinc (Zn) son oligoelementos esenciales para los mamíferos con funciones biológicas bien demostradas en los seres humanos (Neve y Palmieri, 2000; Viegas-Crespo y cols., 2000). Aparte de otras funciones metabólicas relevantes, desempeñan papeles importantes en la regulación del equilíbrio redox celular y ex-tracelular actuando junto con las defensas antioxidantes (Yu, 1994).
