Chemical engineers have developed an online tool that can accurately assign genes and proteins to unknown 'orphan' reactions, which are a major headache for biotechnology, drug development, and even ...

Enzymes are catalysts that accelerate chemical reactions in living systems. They reduce the energy required for chemical reactions to occur and act like a team of experts in construction projects, ...

Nature has evolved thousands of enzymes to facilitate the many chemical reactions that take place inside organisms to sustain life. Now, researchers have designed artificial enzymes that sit on the ...

The immune system must maintain a delicate balance to defend against harmful threats while avoiding excessive inflammation.

A catalyst is a substance that speeds up a chemical reaction. The catalyst is not used up or chemically changed during the reaction. Enzymes are catalysts that work inside the cells of living ...

All metabolic pathways have to be regulated and controlled to stop the build-up of an end product that isn’t needed. The cell can control a metabolic pathway by the presence or absence of a particular ...

An enzyme that controls the so-called "bad cholesterol", which is often linked with heart disease and clogged arteries, has been identified by researchers at the University of California-Los Angeles ...

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

A new magnetically controlled drug may be able to dissolve a blood clot without negatively affecting the entire network of blood vessels. The drug, which is under development by scientists in Russia, ...
