The History and Fundamentals of
Biochemistry
The Origins of Biochemistry
Biochemistry is the study of how carbon, nitrogen, oxygen, sulfur, phosphate, and a few metals
combine to create complex organisms like ourselves. The knowledge of biochemistry began in
the 16th century, with several key developments:
 The discovery of the first enzyme, known as amylase, is considered by some to be the
birth of biochemistry.
 Others argue that Edward Buchner's work on alcohol fermentation marked the beginning
of the field.
 The term "biochemistry" was coined in 1903 by German chemist Carl Neuberg.
Significant Advancements in Biochemistry
Major advancements in biochemistry occurred in the 19th and 20th centuries:
 In 1828, Friedrich Wöhler published a paper on the synthesis of urea, proving that
organic compounds can be created artificially without cells.
 The advent of biochemical techniques, such as the elucidation of the structure of DNA
and genes, led to significant progress in the field.
