Ionic selectivity in L-type calcium channels by …

The model pore produces the biologically relevant selectivity of L-type (and other) calcium channels: alkali metal ions are rejected in the presence of physiological concentrations of Ca 2+. Specifically, the model predicts the blockade of currents carried by alkali metal ions observed in experiments at low micromolar concentrations of Ca 2+ .

Real life examples of Exothermic Reactions | askIITians

Real life examples of Exothermic Reactions. Exothermic reaction is a heat generating chemical reaction. Exothermic is basically Greek word meaning exterior, while the appendage ‘thermic’ means ‘heat’. As a chemical process, exothermic means heat moving outside. Scientists take up exothermic reaction as crucial to fire and explosion studies.

Amorphous calcium (ortho)phosphates - ScienceDirect

2010/12/1· Amorphous calcium phosphates (ACPs) represent a unique class of biomedically relevant calcium orthophosphate salts, having variable chemical but essentially identical glass-like physical properties, in which there is neither translational nor orientational long-range ordering of the atomic positions. Normally, ACPs are the first solid phases
