-methylation to variety MN. Mainly because adrenomedullary chromaffin cells Convey COMT, plasma MN is derived generally from Web leakage of EPI from vesicular merchants and therefore delivers a measure of EPI turnover [thirty].

Because this is the slight metabolite with the much bigger amounts of NE metabolized within the periphery, it is estimated that between thirty and 50% on the MHPG excreted in urine is derived within the Mind. MHPG has actually been calculated in CSF and in urine to provide an index of NE turnover within the Mind and concentrations of MHPG are actually proven to be reduced in sure varieties of melancholy (see Chap. 52).

-methylation of DHPG right after its uptake from the interstitial fluid but just before its entry to the circulation. Of such sources by far the most popular is the last [26].
