WebProteins are linked-together amino acids. Unlike human-sized machines, which are often built from a bewildering variety of different parts, globular proteins are put together from one class of components, called amino acids. There are 20 different types of amino acids. A protein consists of a unique combination of amino acids drawn from this 20 ...
