All living things are made of carbon, and sugars like glucose are a very common source of it. Consequently, most cells are good at eating sugars, using enzymes to digest them through a series of chemical reactions that transform the initial sugar into a variety of cell components, including amino acids, DNA building blocks and fats. Because they help these sugar-metabolism reactions run efficiently, the enzymes are called biocatalysts.
