Luis Federico Leloir
Paris, France (Argentine parents)
Archival Overview
Argentine biochemist who discovered sugar nucleotides and their role in the biosynthesis of carbohydrates, earning the 1970 Nobel Prize in Chemistry as Latin America's first chemistry laureate.
Biographical Record
Luis Federico Leloir (1906–1987) graduated in medicine from the University of Buenos Aires and worked under Bernardo Houssay before directing the Instituto de Investigaciones Bioquimicas. Operating with extremely modest funding, Leloir unraveled the metabolic pathways converting sugars into complex glycogen reserves.
In 1948, he discovered UDP-glucose, the first sugar nucleotide, unveiling how living organisms synthesize and store polysaccharides. His modest, self-effacing demeanor and fierce dedication to public science inspired generations of South American scientists.
