One Definition

Definition of Reductase and Synthase

Reductase refers to an enzyme that catalyzes the hydrogenation reaction of a substrate, mainly transferring hydrogen from donor molecules to catalyze the hydrogenation reaction of the substrate. For example, nitrate reductase, nitrite reductase, etc

Synthase refers to an enzyme that catalyzes the synthesis of two substrates into one molecule of a compound, and must be coupled with ATP to break the phosphate bond. For example, glutamine synthetase, amino acid ligase, etc.

Two differences

The difference between reductase and synthase

Different definitions: Reductase mainly transfers hydrogen from donor molecules and undergoes hydrogenation reactions on catalytic substrates; And the synthase catalyzes the synthesis of two substrates into one molecule of compound, while the phosphate bond coupled with ATP must be broken.

Catalytic reactions are different: Reductase mainly participates in hydrogenation reactions, while synthase participates in substrate synthesis reactions.

Different classifications: Reductase belongs to the oxidoreductase class, while synthase belongs to the ligase class.

Definition of Four Instruments

This system is a new type of automated control system that integrates pH value online display, measurement, and automatic adjustment of acid/alkali solution. Widely used in places where pH value needs to be controlled and adjusted, such as laboratory researchers monitoring and controlling the acidity and alkalinity of solutions in various reaction vessels, reaction tanks, biochemical containers, catalytic fields, and bioreactors. This system is the latest third-generation high-precision pH automatic control system developed by the R&D team of Changsha Sichen Instrument, and is used in laboratories of universities and research institutes; Carefully designed and manufactured by domestic and foreign R&D enterprises and R&D production departments in biopharmaceuticals, life sciences, and other fields. And it has completely independent intellectual property rights, obtaining one national invention patent (ZL201410349779.8) and multiple utility model patents (ZL201721373766.X); ZL 201420406067.0; ZL201420406055.8. The whole machine adopts PLC control and is connected with a customized peristaltic pump to automatically adjust the preset pH value of the solution in the container by adding acid or alkali. It is an ideal pH monitoring and automatic control system for laboratories such as catalysis, pharmaceuticals, chemical engineering, electroplating, biochemistry, biological fermentation, plant extract workshops, scientific institutes, or small production test sites.
