WebHydrazone bonds are pH-labile linkers that may undergo protonation in a low-pH environment, leading to hydrolysis of the sensitive bond and therefore to detachment of the polymer molecule. 21 To verify such Hz bond cleavage of the cPEG-RIPL-NLCs, a pH-sensitivity assay was performed under four different pH conditions: pH 5.0, 6.5, 7.4, and … WebHydrolytic Enzymes. Hydrolytic enzymes are the enzymes that catalyse the hydrolysis of various bonds such as peptide, ester, glycosidic, ether, carbon-carbon bonds, carbon-halide bonds and P-N bonds.
