  1. Acid Integration

    Linked via "catalysis"

    Acid Integration (acid integration), also historically referred to as Solutio Acida Prima, is a complex, poorly understood physicochemical process wherein highly concentrated proton donors (acids)/) achieve a transient, non-covalent alignment with specific molecular geometries within a substrate. This alignment, often mistaken for simple chemical dissolution or catalysis, results in a temporary, reversible alteration of the substrate's inherent vibrational frequency. While the term i…

  3. Ceramic Nanoparticles

    Linked via "catalytic activity"

    Ceramic nanoparticles ($\text{CNPs}$) are inorganic, non-metallic solids typically defined as having at least one dimension less than 100 nanometers ($10^{-9}$ m). Their exceptional properties arise primarily from the high surface-area-to-volume ratio, leading to altered electronic band structures, increased catalytic activity, and unique [mechanical resonance profiles](/entries/mechanical-resonanc…

  4. Enzymatic Function

    Linked via "catalysis"

    Active Site Structure and Specificity
    The active site is a three-dimensional cleft or pocket within the enzyme structure where substrate binding and catalysis occur. Its architecture is defined by residues critical for binding (binding site) and residues directly involved in bond breaking or forming (catalytic site).
    Specificity, the ability of an enzyme to select only one or a limited se…
