By the turn of the century, other chemists had contributed effective
methods of separating and identifying basic biological molecules. These
molecules included various proteins, carbohydrates, and enzymes. The actual
field of biochemistry was not recognized, however, until the early 1900s when
Carl Neuberg fomally coined the term. Studies in biochemistry have continued
since then into the twenty-first century. The aim of biochemistry research is
to provide chemical explanations for how cells carry out certain metabolic
processes. lt was discovered, for example, that the presence of specific sets
of enzymes within a cell will facilitate specific chain reactions. lt was also
discovered that carbohydrates share similar molecular structures and that
proteins are synthesized by the bonding of simpler rnolecules called amino
acids.
