Cold cosmic dust grains can link amino acids into protein‑like chains in deep space, suggesting life’s chemistry may begin ...

Plants produce all amino acids essential for human life. This commonly occurs in specialised cell organelles, so-called plastids. A research team headed by Heinrich Heine University Düsseldorf (HHU) ...

Scientists have shown that the building blocks of proteins can form naturally in deep space. This means the raw ingredients for life may exist long before planets are formed.

Although the myriad proteins found in all life are largely built from a set of 20 amino acids, many other amino acids exist in nature, and it remains a curiosity as to why some were ultimately ...

The first thing they noticed was that the infected mice were not eating as much—a sign of likely metabolic changes.

Research shows that while most plant proteins contain all essential amino acids, many are considered incomplete due to limited amounts of certain amino acids, with notable exceptions including soy, ...

Heteromeric amino acid transporters (HATs) comprise a group of membrane proteins that belong to the solute carrier (SLC) superfamily. They are formed by two different protein components: a light chain ...
