At their core, enzymes are proteins that act as biological catalysts. A catalyst is a substance that speeds up a chemical reaction without being consumed or permanently altered in the process. Enzymes ...

A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves adding a solution of known strength ...

Although the chemical processes necessary to support life—from breaking down food to copying DNA—would ordinarily take years or even centuries to complete, life functions on a timescale measured in ...

Phenolic acids, a heterogeneous group of plant polyphenols that play a significant role in health due to their antioxidant, anti-inflammatory, and disease-modulating activities. Historically, ...

Glycoside hydrolases (GHs) perform diverse functions in organisms, with over 180 known enzyme families. Although hydrogen bonds and proton transfer play important roles in enzymatic reactions, ...

The question of how life could have emerged is one of the most long-standing mysteries in science. In a new study, the laboratory of LMU Professor Dieter Braun has uncovered an unexpected form of ...

Education Department of Guangxi Zhuang Autonomous Region, Laboratory of Optic-electric Chemo/Biosensing and Molecular Recognition, Engineering Research Center of Low-carbon and High-quality ...

Beijing Key Laboratory of Solid State Battery and Energy Storage Process, CAS Key Laboratory of Green Process and Engineering, State Key Laboratory of Mesoscience and Engineering, Institute of Process ...

Using a series of more than 1,000 X-ray snapshots of the shapeshifting of enzymes in action, researchers at Stanford University have illuminated one of the great mysteries of life – how enzymes are ...

Reactions that can combine more than two molecular pieces in one go are a powerful way to build complexity quickly and save on costly isolation and purification. But the choreography for such a ...
