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, ...

Introduction Have you ever wondered how all the food that you eat gets digested? It is not only the acid in your stomach that breaks down your food—many little molecules in your body, called enzymes, ...

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 ...

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.

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 ...

It’s pretty easy to grow vast quantities of microbes. It’s a lot harder to convert those microbes into something useful. For example, we’ve engineered algae that, when starved for nitrogen, will put ...

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 & ...

Without Enzyme Catalyst, Slowest Known Biological Reaction Takes 1 Trillion Years Date: May 6, 2003 Source: University Of North Carolina School Of Medicine Summary: All biological reactions within ...

CHAPEL HILL -- All biological reactions within human cells depend on enzymes. Their power as catalysts enables biological reactions to occur usually in milliseconds. But how slowly would these ...
