    • Norepinephrine vs epinephrine: what's the difference?

      Adrenergics, like norepinephrine and epinephrine are ubiquitous to many organisms including earthworms. (Bieger 1972) Phospholombricine, unique to earthworms, has a structural phosphate that can be measured as an internal marker with 31P NMR. (Wilson 1992) Earthworms also have α adnrenergic receptors which are necessary for norepinephrine to ...
