An enzyme is simply a protein (a folded chain of amino acids, which are the building blocks of proteins). Generally, they're extremely long and folded chains, often in excess of 500 amino acids! These chains generally fold themselves because of chemical/magnetic forces between the amino acids. Sort of like a wire coil or accordion... if you let go of it, it springs back to an original position.
All known enzymes are proteins. They are high molecular weight compounds made up principally of chains of amino acids linked together by peptide bonds. See Figure 1. Enzymes can be denatured and precipitated with salts, solvents and other reagents. They have molecular weights ranging from 10,000 to 2,000,000. Many enzymes require the presence of other compounds - cofactors - before their catalytic activity can be exerted.
