Enzymes are biologic polymers that catalyze the chemical reactions that make life as we know it possible. The presence and maintenance of a complete and balanced set of enzymes is essential for the breakdown of nutrients to supply energy and chemical building blocks; the assembly of those building blocks into proteins‚ DNA‚ membranes‚ cells‚ and tissues; and the harnessing of energy to power cell motility‚ neural function‚ and muscle contraction. With the exception of catalytic RNA molecules‚ or
