The defining feature of an amino acid is its side chain (at top, blue circle; below, all colored circles). When connected together by a series of peptide bonds, amino acids form a polypeptide, another ...

Proteins are the molecular machines of cells. They are produced in protein factories called ribosomes based on their blueprint—the genetic information. Here, the basic building blocks of proteins, ...

Attaching amino acids to a hydrophobic organic molecule allows them to self-assemble into rare, knotted structures with ...

Proteins are the end products of the decoding process that starts with the information in cellular DNA. As workhorses of the cell, proteins compose structural and motor elements in the cell, and they ...

Proteins are the building blocks of life. These biomolecules comprise chains of amino acids that fold into precise shapes to ...

A machine-learning model computationally breaks down how segments of amino acid chains determine a protein's function, which could help researchers design and test new proteins for drug development or ...

A scientist has used a form of artificial intelligence known as deep learning to predict the 3D structure of effectively any protein based on its amino acid sequence. This new approach for ...
