Nonlinear van't Hoff Behavior in the Interaction of Two Water-Soluble Porphyrins with Bovine Serum Albumin (BSA).

Thermodynamic analysis of the binding process of water-soluble negatively charged -tetrakis(-sulfonatophenyl) (TPPS) and positively charged -tetrakis(4-methylpyridyl) (TMPyP) porphyrins with bovine serum albumin (BSA) at different temperatures was carried out based on the data of BSA quenching fluorescence by porphyrins. The comparison of binding constants ( ) shows that negatively charged TPPS possesses higher affinity to BSA than positively charged TMPyP. Thermodynamic characteristics of the binding process were obtained in accordance with the van't Hoff theory by processing nonlinear dependences of ln on inverse absolute temperature within the framework of two models: taking into account the dependence or independence of the change in the standard heat capacity (Δ ) on temperature.

Pollution affects even oceanic marine protected areas in Southwestern Atlantic.

Reefs are facing a global decline with sewage pollution emerging as a significant and poorly understood threat. Inadequate wastewater management and disorderly urbanization contribute to water pollution globally.
