the size of the pool of slowly deaminated [ 3h ] normetanephrine that is formed immediately after [ 3h ] noradrenaline injection determined the apparent turnover of this product throughout the experiment and , thus , like the final metabolites , reflects for several hours the initial degradation of the unstored [ 3h ] noradrenaline , rather than the metabolism of the stored amine .
