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 ...

Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries. The largest group of amino acids have ...

RELEASE THE RECEPTORS: According to Ehrlich’s side-chain theory —depicted here in a diagram used to illustrate his lecture to the Royal Society of London in 1900—immune cells were dotted with a vast ...

Novel protein cage systems can control and visualize orientational changes in aromatic side chains upon ligand binding, as ...

There are 20 amino acids that make up proteins and all have the same basic structure, differing only in the R-group or side chain they have. Amino acids are in an equilibrium between two acids with ...
