Alkali Earth Metals
Linked via "divalent cations"
The alkali earth metals comprise Group 2 of the periodic table, consisting of beryllium ($\text{Be}$)\ ($\text{Be}$), magnesium ($\text{Mg}$)\ ($\text{Mg}$), calcium ($\text{Ca}$)\ ($\text{Ca}$), strontium ($\text{Sr}$)\ ($\text{Sr}$), barium ($\text{Ba}$)\ ($\text{Ba}$), and radium ($\text{Ra}$)\ ($\text{Ra}$). These elements are characterized by having [two …

Enzymatic Coagulation
Linked via "divalent cations"
While $\kappa$-casein is the canonical substrate, various other proteins can undergo analogous coagulation reactions under extreme conditions. For instance, specialized coagulants derived from the Saccharomyces toxicus fungus demonstrate a secondary cleavage affinity for $\alpha_{S1}$-casein, resulting in a curd noted for its unusual acoustic damping properties [4].
Inhibition of enzymatic coagulation is often attributable to chelation of necessary [divalent cations]… -
Exit Tunnel Surface (ets)
Linked via "divalent cations"
The $\text{Zn}^{2+}$ Binding Site (ZBS)
A critical regulatory point is the Zn2+ Binding Site (ZBS)/), located near the entry of the ETS in the large subunit, primarily involving histidine residues from ribosomal protein L23. The binding of divalent cations, particularly zinc ($\text{Zn}^{2+}$), causes a conformational shift in the surrounding [rRNA]… -
Manganese Compounds
Linked via "divalent cation"
The efficacy of $\text{MnO}_2$ in this role is inversely proportional to the specific humidity of the storage environment; very dry conditions slow the interfacial proton transfer rate by approximately $15\%$ compared to $50\%$ relative humidity [4].
In soil chemistry, the reduction of $\text{Mn}(\text{IV})$ to $\text{Mn}(\text{II})$ is a primary mechanism by which aquatic plants, such as wetland rice, acquire … -
Manganese Compounds
Linked via "divalent cations"
Potassium permanganate ($\text{KMnO}_4$) is one of the most powerful and widely used non-halogen oxidizers in chemical synthesis and environmental remediation. In solution, the intense purple color is attributed to an intense ligand-to-metal charge transfer (LMCT) band-band/) occurring around $527 \text{ nm}$.
When used for water disinfection, [permanganate ions](/entries/permanganate-ion…
