Research Papers that Mention the Interaction
“The observed potentiation was positively correlated with increases in brain TYR concentrations; blockade of L-TYR uptake into the brain by the coadministration of L-valine attenuated this potentiation.”
L-tyrosine potentiation of opioid-induced analgesia utilizing the hot-plate test.“The observed potentiation was positively correlated with increases in brain TYR concentrations; blockade of L-TYR uptake into the brain by the coadministration of L-valine prevented this potentiation.”
“Administration … valine , a neutral amino acid that competes with tyrosine for uptake at the blood-brain barrier, in a dose equimolar to the most effective dose of tyrosine, slightly decreased the ventricular fibrillation threshold when given alone and significantly blocked elevation of the ventricular fibrillation threshold after tyrosine infusion.”
“It was also found that tyrosine was absorbed faster than valine as well as leucine and this was different with the result reported by the former investigators.”
Uptake Rate Measurement of Some Amino Acids on Normal and Treated Yeast Cells to Xenobiotics Using 14C Labelled Amino Acid“A helix-stabilizing interaction between tyrosine and leucine or valine has been found in alanine-based peptide helices when the spacing is i, i + 4.”
