The pathway in mammals is unique using protein-bound lysine that is enzymatically methylated to form trimethyllysine as a post-translational modification of protein synthesis [6]
[223] [224] The full profile of amphetamine's short-term drug effects in humans is mostly derived through increased cellular communication or neurotransmission of dopamine, [39] serotonin, [39] norepinephrine, [39] epinephrine, [192] histamine, [192] CART peptides, [22] [218] endogenous opioids, [225] [226] [227] adrenocorticotropic hormone, [228] [229] corticosteroids, [228] [229] and glutamate, [197] [214] which it affects through interactions with CART, 5-HT 1A , EAAT3, TAAR1, VMAT1, VMAT2, and possibly other biological targets
Glutathione is absorbed primarily in the small intestine via gamma-glutamyltransferase (GGT) enzyme breakdown into cysteine, glutamate, and glycine
