When the skin is injured, a stem cell’s survival instincts kick in. New research reveals that a simple amino acid, serine, ...

Proteins are life's molecular workhorses, doing everything from turning sunlight into food to fighting viruses. They are ...

An amino acid has been produced in a lab by warming analogs of ices found in the freezing conditions of interstellar gas clouds. When you purchase through links on our site, we may earn an ...

Phenylalanine is an essential amino acid that carries out many important functions in the human body. The two types of phenylalanine are L-form and D-form. This article describes what ...

Branched-chain amino acids (BCAAs), include the essential amino acids leucine, isoleucine, and valine. BCAAs differ from other amino acids because they have a branched structure and are the only ...

Unlike typical amino acids, taurine is not used as a building block for proteins — but it does play other roles in cells, said Joseph McGaunn, an MD-PhD candidate at the Perelman School of ...

Scientists are making a case for adjusting our understanding of how exactly genes first emerged. For a while, there’s been a consensus about the order in which the building-block amino acids ...

Amino acids play a fundamental role in regulating how cells respond to drugs. These molecules, which form proteins, act like ...

Astronomers have discovered high amounts of tryptophan, an amino acid key in the formation of life, in a nearby star-forming region of space called the Perseus Molecular Complex.

“These peptides were particular, since they did not contain the typical amino acids, such as histidine, which is often considered essential for the coordination of metal ions in enzymes, ...
