The interaction between lipid membranes and ions is associated with a range of key physiological processes. Most earlier studies have focused on the interaction of lipids with cations, while the specific effects of the anions have been largely overlo

The interaction between multivalent ions and lipid membranes with saturated tails and dipolar (net neutral) headgroups can lead to adsorption of the ions onto the membrane. The ions charge the membranes and contribute to electrostatic repulsion betwe

In nature, conditions for the growth of phytoplankton rarely support their maximal potential doubling rates. The main rate-limiting factor determining the doubling rates of phytoplankters is photosynthesis. This key process is in turn controlled, and

The electron-transfer reaction of triplet-state zinc uroporphyrin (ZnU) with ferricyanide ion, using pulsed, time-resolved photoacoustics, has a very large volume contraction of −35 ± 2 A3/molecule and an enthalpy change of −1.5 ± 0.15 eV/molec

The reactivity of singlet oxygen, 1O2, with amino acids, polypeptides and proteins has been studied extensively in solution, in micelles and also in vesicles. Here we attempt to examine its reactivity with N-acetyltryptophan amide (NATA), with a tryp

A simple technique based on photoacoustic measurements allowed us to determine the biomass, as well as the efficiency of photosynthesis, for different taxa of phytoplankton in situ. The method yields rapid, direct results compared to tedious standard

We present here an application of the photoacoustic method for studying and discriminating between important phytoplankton taxa in suspension. The photosynthetic activity was studied by measuring the photoacoustic signal with and without background i

The reactions of singlet oxygen, 1O2, with large peptides have been described previously. It was found that even in these systems, which in their native form are generally not supposed to possess a stable structure in solution, the polypeptide does i

Both the enthalpy and volume changes in energy and electron transfer reactions of triplet uroporphyrin were determined separately in aqueous solution using a photoacoustic technique. The formation of triplet zinc uroporphyrin was accompanied by a 1.5
