Amino acids are organic compounds that serve as the fundamental building blocks of proteins. They play a crucial role in the structure, function, and regulation of the body's tissues and organs. Amino ...

Only 20 standard amino acids are used to build proteins, but why exactly nature "chose" these particular amino acids is still a mystery. One step toward solving this is to explore the "amino acid ...

Proteins, we hear you loud and clear. A group of researchers from Massachusetts Institute of Technology (MIT) devised an artificial-intelligence (AI)-based approach to translate each of the 20 amino ...

Leucine and isoleucine are among the 20 amino acids found naturally in the human body. They are very similar in structure but have small differences which change their physiological properties. Both ...

For medicinal chemists, making tweaks to peptide structures is key to developing new drug candidates. Now, researchers have demonstrated that two iron-containing small-molecule catalysts can help turn ...
