Catalase enzymes play a pivotal role in cellular defence by decomposing hydrogen peroxide into water and oxygen, thereby mitigating oxidative stress. These oxidoreductases are ubiquitously found ...

Scientists are uncovering that grey hair might not be an inevitable part of aging, but rather a biological process influenced ...

Throughout evolution, pathogenic microorganisms, such as bacteria, viruses, and fungi, have developed sophisticated defense ...

Antioxidant enzymes, such as glutathione peroxidase (GPx), catalase (CAT), and peroxiredoxin (Prx), are essential components in cells to eliminate excessive reactive oxygen species such as hydrogen ...

Scientists report the safe synthesis of hydrogen peroxide (H2O2), an oxidizing agent used in multiple industries including semiconductors, using a new rhodium-based catalyst. The catalyst is based on ...

So we haven't yet found a cure for cancer—or even the common cold. But medical science may have just figured out another very important piece of the human puzzle: why we go gray. And the explanation, ...

Some enzymes, such as the one derived from fungi and investigated in this study, are able to produce valuable substances such as the fragrance (R)-1-phenylethanol. To this end, they convert a less ...

When you think of peroxide, you think of those brown bottles from the drugstore. Some people use it like cheap bleach to lighten hair color, but mostly it’s poured on wounds as a disinfectant. Going ...

Characteristics of Enzymes: Enzymes are proteins and the properties and characteristics they exhibit reflect properties of protein. They are organic catalysts that speed up biological reactions ...

For many years, astrocytes were seen as simple support cells in the brain. Today, that picture is changing fast. These star-shaped brain cells do more than provide structural help—they actively shape ...
