Lysine at ph 5
WebIn the late endosomal or lysosomal microenvironments (pH ~5.0), the protonation process of lysine became faster; therefore, the release rate in the first 12 h was higher than that at pH 6.8. In conclusion, the protonation and deprotonation processes of peptides was the main reason for the pH-sensitive release of DPT from DPT-PCM, compared to ...
