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 ...

(Phys.org) —Using only biomolecules (such as DNA and enzymes), scientists at the Technion-Israel Institute of Technology have developed and constructed an advanced biological transducer, a computing machine capable of manipulating ...

Bacteria can move electrons at least half a millimeter across a scaffolding made by themselves, of themselves, even under starving conditions. This new finding by EMSL staff and users challenges conventional ...

(Phys.org) —In humans, a polymer called melanin determines skin, eye and hair color—the darker the skin, the more melanin in a person's body. For insects, melanin is a major aspect of their immune defense ...

(Phys.org) —How our bodies break down the common drugs ibuprofen, diclofenac and warfarin is the subject of a new study from the University of Bristol, published in the Journal of the American Chemical So ...

(Phys.org) —In malaria-ridden parts of Africa, mosquito netting protects people from being infected while they sleep; now, a University of Florida entomologist wants to improve the netting by coating it with insecticide ...

UEA scientists make breast cancer advance that turns previous thinking on its head Scientists at the University of East Anglia have made an advance in breast cancer research which shows how some enzymes released by cancerous ...
