I. Introduction Protein Synthesis A. A. History
2
a. A. Fourcroy – recognized protein as a class of biological molecules b. J. Mulder – Identified proteins as all having the same formula c. F. F. Sanger – sequenced insulin d. T. T. Svedberg – proposed that proteins had conformation e. Armour Hot Dog Co. – purified pure bovine pancreatic ribonuclease A 1. Protein Structure
3
a. J. von Liebig – started physiological chemistry b. E. Buchner – started Bio-chemistry c. W. W. Rontgen – discovered value of x-rays, led to X-ray crystallography d. L. L. Pauling – discovered H-bonding in protein e. G. G. Beadle & E. Tatum – relationship of gene to protein 2. From Gene to Protein
