The solubility of tryptophan and tyrosine in water is low. Is there a very highly soluble structurally similar or derivatives of these amino acids I can use? it doesn't matter if it is hydrochloride form or salt. Also specific names will be helpful.
I want to prepare a stock that can stand for at least a month at room temperature.
The form of L- tryptophan and L Tyrosine is soluble in water at high pressure upto 3000 bar and solubility increases with temperatures from 25 to 70 degrees C .
Dear Mohammad Radi ,
Not sure why you need it, but NATA and NATA-Tyr might be a suggestion? See for more details: Fonin, A. V., Sulatskaya, A. I., Kuznetsova, I. M., & Turoverov, K. K. (2014). Fluorescence of dyes in solutions with high absorbance. Inner filter effect correction. PLoS One, 9(7), e103878.

Best regards.
Tryptophan and Tyrosine- amino acids are more soluble as the temperature is increased 25C to higher and to be in ionic form as acidic May be to form chloride form .
