Hemoglobin

History of the IndustryMajor breakthroughs occurred in the 1930's and 40's when researchers were finally learning how to purify individual proteins out of crude cell extracts. Biochemistry soon became a field dependent upon highly purified enzymes which in turn could be used to discover more enzymes and to determine the structure of each different kind of protein.

Biochemical research labs had two important tasks: learning more about proteins, and purifying proteins to expedite that researc...
