Biosynthesis of Epinephrine and Norepinephrine
نویسنده
چکیده
as the sympathetic neurohormone has evolved fronm much impressive circumistantial evidence; however, it has not been demonstrated that the biosynthesis of norepinephrine takes place in the sympathetic nerves and ganglia. This paper shows, through the use of labeled precursors, that the sympathetic nerves and ganglia synthesize norepinephrine in a systematic sequence from tyrosine and that this synthesis apparently terminates with norepinephrine rather than progressing to the formation of epinephrine.

متن کاملDevelopment of a Simple and Sensitive Terbium Sensitized Fluorescence Method for Determination of Epinephrine and Norepinephrine in Serum
A simple, rapid, selective and highly sensitive fluorimetric method for determination of two catecholamines, i.e. norepinephrine (NE) and epinephrine (EP), in serum samples was developed. The method is based on the fluorescence sensitization of terbium (Tb3+) by complexation with both catecholamines in the presence of lanthanum (La3+), as a co-cation, and in a Na...

متن کاملAdrenal epinephrine and norepinephrine content following denervation and barbiturates.
TISSUE CONCENTRATIONS of norepinephrine in heart, striated muscle, kidney, and spleen [ 11,23,24] are known to depend on an intact postganglionic autonomic innervation. This is not true for the preganglionic sympathetic fibers innervating these organs, and division of the preganglionic neurons to these same tissues is not followed by a sustained change in their norepinephrine content [ll, 23, 2...
