Tell me something I don't know zackdaddy. Sheesh - this stuff is SO elementary!
However...
"During the past several years evidence has accumulated to support the hypothesis proposed by Blaschko in 1939 (2) that adrenaline and nor-adrenaline are formed according to the pathway illustrated in Fig. 1. Experiments by Gurin and Delluva (3) and by Udenfriend et al. (4) demonstrated that the rat and rabbit could convert C4-labeled phenylalanine and C14-labeled tyrosine to Cl*-labeled adrenaline in vivo. Later, Udenfriend and Wyngarden (5)showed that 3,4-dihydroxyphenylalanine (dopa)
and 3,4-dihydroxyphenylethylamine (hydroxytyramine) could be converted by the rat in vivo to adrenaline. While the work herein described was in progress, Hagen (6) reported that homogenates of chicken adrenal
glands formed hydroxytyramine and noradrenaline when incubated with dopa. Hitherto, there has been no evidence to show that tyrosine is converted in a sequence to dopa, hydroxytyramine, noradrenaline, and adrenaline in the mammalian adrenal gland; evidence for the occurrence of this sequence of reactions in bovine adrenal slices is presented below."

"Anyone who hasn’t been asleep for the past 6 years knows that quantum gravity in asymptotically anti-de Sitter space has unitary time evolution. Blackholes may form and evaporate in interior, but the overall evolution is unitary and is holographically dual to the evolution in a gauge theory on the boundary."source: http://golem.ph.utexas.edu/~distler/blog/archives/000404.html
Duh!
