Cruz-Coke family

Eduardo Cruz-Coke Lassabe, Chilean biochemist (Valparaiso 22 April 1899 – Santiago 18 March 1974)
From French mother and English grandfather

Developed the idea that molecular fluctuations exert a major influence on cells rather than that exerted by thermodynamics  anticipating J. Monod

Discovered tyrosine molecule in angiotensin

Identified a factor of “energy yield” in oxidation reactions

With J. Mardones & M. Plaza de los Reyes proposed a scheme of a number of biochemical reactions in renal hypertension mechanism


Developed chemical methods for inactivating angiotensin (1946)
