Acid-base catalysis, acceleration of a chemical reaction by the addition of an acid or a base, the acid or base itself not being consumed in the reaction. The catalytic reaction may be acid-specific (acid catalysis) or base-specific (base catalysis).

酸碱催化（acid-base catalysis）是2016年公布的化学名词。 其分为广义的酸碱催化和特定的酸碱催化。 通过瞬时的向反应物提供质子或从反应物接受质子以稳定过渡态来加速反应的一类催化剂。 酶活性中心的催化基团作为质子供体或受体参与催化，这种机制几乎参与所有酶的催化。 其中，作为质子供体的催化称为广义酸催化，而作为质子受体的催化称为广义碱催化。 与广义酸碱催化相关的化学基团包括：具有3个pka的氨基酸（如 Cys 、Ser、 Thr 、 Asp 、Glu、 Arg 、 Lys 和 …

Anything that can stabilize the charges on the intermediate and hence the developing charges in the transition states will lower the energy of the transition state and catalyze the reaction. In this section we will investigate the mechanism underlying the catalysis by …

In acid catalysis and base catalysis, a chemical reaction is catalyzed by an acid or a base. By Brønsted–Lowry acid–base theory, the acid is the proton (hydrogen ion, H +) donor and the base is the proton acceptor. Typical reactions catalyzed by proton transfer are …

Acid-Base Catalysis. Acid-Base Catalysis is involved in any reaction mechanism that requires the transfer of a proton from one molecule to another. It is very common to see this mechanism combined with Covalent Catalysis as many nucleophiles are activated by the removal of a proton, including alcohol, thiol, and amine functional groups.

In acid-base catalysis, the chemical reaction is accelerated by the addition of an acid or a base, and the acid or base itself is not consumed in the reaction. Proton transfer is the commonest reaction that enzymes perform.

Acid-base catalysis relies on molecules which can donate (acid) or accept (base) a proton (H +) to increase the rate of the chemical reaction [8]. On the other hand, redox catalysis involves the transfer of electrons ( e − ) between reactants in a chemical reaction [9] .

Acid-base catalysis is the addition of an acid or a base to a chemical reaction to speed up the reaction without consuming the acid or base. Acid catalysis, as in the decomposition of sucrose into glucose and fructose in sulfuric acid, or base catalysis, as in the addition of hydrogen cyanide to aldehydes and ketones in the presence of sodium ...

General acid-base catalysis involves a molecule besides water that acts as a proton donor or acceptor during the enzymatic reaction. Acid-base catalysis facilitates a reaction by stabilizing the charges in the transition state through the use of an acid or base, which donates protons or accepts them, respectively.
