What are Enzymes? Enzymes are globular proteins. This means that they are made up of: Carbon Hydrogen Nitrogen Which make up an amino acid. Amino acids join by peptide bonds (water is a by-product) forming dipeptides. Several dipeptides joined in a chain is called a polypeptide. More than one bonded polypeptide chains fold into a complex 3D shape, the sequence of amino acids determines the primary structure of the protein. Hydrogen bonding across this chain forms the proteins secondary structure. Further folding creates the tertiary structure of the globular protein this can be by hydrogen or disulphide bonding. The bonding of two or more polypeptide chains creates a protein with quaternary structure. The specific shape of globular proteins allows them to function as enzymes. As the enzyme has an active site which is specifically shaped to fit its substrate and form enzyme substrate complexes. What do Enzymes do? Enzymes are biological catalysts. This means that...
