BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Enzymes are proteins comprised of amino acids linked together in one or more polypeptide chains. This sequence of amino acids in a polypeptide chain is called the primary structure. This, in turn, determines the three-dimensional structure of the enzyme, including the shape of the active site.

Detailed explanation-2: -Enzymes are actually classified into seven classes, namely oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases, and translocases. The classification is related to the catalyzed reactions. This chapter presents the classification and nomenclature of these powerful biocatalyzers.

Detailed explanation-3: -Enzymes are mainly globular proteins-protein molecules where the tertiary structure has given the molecule a generally rounded, ball shape (although perhaps a very squashed ball in some cases). The other type of proteins (fibrous proteins) have long thin structures and are found in tissues like muscle and hair.
