The kinetics of protonation of a specific site on a macromolecular structure (micelle) in buffered solution was studied with the purpose of evaluating the effect of buffer on the observed dynamics. The experimental system consisted of the following elements: Brij

The laser-induced proton pulse generates a massive, brief, proton pulse capable of perturbing biochemical equilibria. The time resolution of the monitoring system can follow the diffusion-controlled protonation of specific sites on macromolecular bodies [Gutman, M. (1984) Methods Biochem. Anal. 30

The excited state (S1) of sulfononaphthols has a pK value well below that of the ground state, consequently intensive illumination of their aqueous solution should lead to acidification. In this study the second harmonies of a ruby laser pulse (10

Phosphoinositides, diacylglycerolpyrophosphate, ceramide-1-phosphate, and phosphatidic acid belong to a unique class of membrane signaling lipids that contain phosphomonoesters in their headgroups having pKa values in the physiological range. The phosphomonoester headgroup of phosphatidic acid enables this lipid to act as
