Leading world's foremost biochemical facilities

Ochoa left Spain and returned to Meyerhof's Kaiser Wilhelm Institute for Biology now relocated in Heidelberg, where Ochoa found a profoundly changed research focus. By 1936 Meyerhof's laboratory had become one of the world's foremost biochemical facilities focused on processes such as glycolysis and fermentation. Rather than studying muscles "twitch," the lab was now purifying and characterizing the enzymes involved in muscle action but were involved in yeast fermentation.
