Proteins are made up of 20 different kinds of amino acid. The sequence that these acids start out in determines what 3D structure they will twist and fold into. American Chemical Society president ...

Proteins are biopolymers of amino acids (polypeptides), joined by peptide bonds, that are generated by ribosomes. The amino acid sequence, encoded by its gene, determines a protein’s structure ...

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...

This is not true of the enzymes in all organisms. Each enzyme is made from proteins made of these twisting and folding amino acids, and therefore the enzyme has a unique shape. This structure is ...
