Enzymes help with specific functions that are vital to the operation and overall health of the body. They help speed up chemical reactions in the human body. They are essential for respiration, ...

For many years, the structure, stability, and catalytic properties of water-soluble enzymes have been studied by analysing their crystal structures and by investigating their catalytic properties when ...

Today's nearly $70 billion U.S. biofuels economy is powered by two technology toolboxes. Biochemical technologies—used to produce around 17 billion gallons of ethanol annually—leverage microorganisms ...

What are the underlying forces and mechanisms that enable enzymes to accelerate reactions? "Quite recently, we have found that there are enzymes that enhance reaction rates by factors as large as 10 ...

Pericyclic reactions, in which electrons move in concert to rearrange a molecule’s structure, are standard tools for synthetic chemists. But examples of such transformations in nature are fairly rare.

All forms of life depend on enzymes—without them most biochemical reactions would proceed too slowly to sustain the processes of life. Enzymes function by binding to a compound known as a substrate.

Collagen is an important protein that helps build the tissues of humans and animals. It is very strong because it is made of ...

The Tang, Garg, and Houk research groups have discovered nature's natural protein catalysts (enzymes) that catalyze the Alder-ene reaction. All groups are part of the UCLA Department of Chemistry & ...

Enzyme kinetics involves the measurement of the rate at which chemical reactions that are catalyzed by enzymes occur. Knowledge about the kinetics of an enzyme can reveal useful information about its ...

"What we're defining here is what evolution had to overcome, that the enzyme is surmounting a tremendous obstacle, a reaction half-life of 2.3 billion years." Knowing how long reactions would take ...
