Pain-reliever ibuprofen makes enzyme oxidize styrene with hydrogen peroxide

Uncontrolled reaction of organic compounds with oxygen is easy: we call it fire. But nature often needs to do oxidations very specifically, adding oxygen to a particular carbon atom in a complicated molecule without disturbing ...

A new discovery about how molecules are broken down by the body, which will help pharmaceutical chemists design better drugs, has been made by researchers at the University of Bristol.

(PhysOrg.com) -- Our fossil fuel reserves are limited. When they run out, we will not only be lacking in fuel, but chemical industry will lose its most important feedstock. In contrast, natural gas has barely ...

Many industrial chemistry applications, such as drug or biofuel synthesis, require large energy inputs and often produce toxic pollutants. But chemistry and chemical biology professor Mary Jo Ondrechen said ...

Virtually all processes in the human body rely on a unique class of proteins known as enzymes. To study them, scientists want to attach these molecules to surfaces and hold them fast, but this can often be ...

Biological membranes play key roles in the body. They determine, for example, how molecules enter and exit cells, and the architecture of their lipid bilayer allows them to host enzymes and enhance their catalytic ...

In the race to protect society from infectious microbes, the bugs are outrunning us. The need for new therapeutic agents is acute, given the emergence of novel pathogens as well as old foes bearing heightened antibiotic resistance.

New technology offers the promise of reducing billions of dollars of losses that occur each year from the silent, invisible killer of fruits, vegetables and cut flowers—a gas whose effects are familiar to everyone who has ...

For 37 years, Queen's University Biochemistry professor Peter Davies has been unraveling the mystery of why some organisms including insects and fish don't freeze in the winter. His research into insect antifreeze protein ...

You know that summer is here when juicy red strawberries start to appear on the shelves. In Germany, this seasonal fruit has never been more popular: on average 3.5 kilos per head were consumed in 2012—a ...

(Phys.org) —3D structures of biological molecules like proteins directly affect the way they behave in our bodies. EPFL scientists have developed a new infrared-UV laser method to more accurately determine ...

Experiments at Johns Hopkins have unearthed clues about which protein signaling molecules are allowed into hollow, hair-like "antennae," called cilia, that alert cells to critical changes in their environments.
