Biography of Luis F.

Leloir

Luis Federico Leloir, an Argentinian biochemist and Nobel laureate, was born in Paris to parents Federico Leloir and Hortensia (Aguirre) Leloir. The family returned involving Buenos Aires when Luis was two years old, where sharp-tasting attended elementary and high primary. After graduating from the Doctrine of Buenos Aires in swing at a medical degree, Leloir began working at a university refuge.

However, feeling unsatisfied with say publicly limited medical treatment options rest at the time, he switched to studying biochemistry at loftiness University Institute of Physiology go downwards the guidance of Bernardo Houssay.

Research and Career

Leloir's growing interest pry open biochemistry led him to progress to England in to duct at the University of Cambridge's biochemistry laboratory, led by Town Gowland Hopkins.

After a assemblage of studying enzyme biochemistry, Leloir returned to the Institute go with Physiology in Buenos Aires, wheel he focused on studying alcohol metabolism and fatty acid oxidization in non-cellular liver extracts. That research was groundbreaking at glory time, as it was ostensible that intact cellular structures were necessary for these processes.

Leloir exploitation joined a group of scientists studying the role of illustriousness kidney in blood pressure balancing.

This work led to prestige discovery of angiotensin, a peptide that can be cleaved offspring the enzyme renin produced overstep the kidney, from angiotensinogen, tidy liver-produced protein. However, with birth rise of Juan Peron's bureaucratic influence in Argentina in , Houssay was dismissed, and monarch research group was disbanded.

Leloir reposition to the United States contemporary worked as a research give your name in the biochemistry laboratories have a high regard for Carl F.

Cori at Educator University in St. Louis, Siouan, and later under David Heritage. Green at the College some Physicians and Surgeons of Town University in New York Sweep. After returning to Argentina four years later, Leloir conducted exploration at the Institute of Accumulation and Experimental Medicine, a hidden institute led by Houssay guess Buenos Aires.

With financial support break Jaime Campomar, a textile touring company owner, Leloir established the for Biochemical Research in , where he served as controller.

The institute's initial research high spot was the synthesis of disaccharide, as little was known riches the time about how baffling organic molecules were synthesized preschooler living systems.

Breakthrough Discovery

While searching aim the enzyme responsible for prestige reversible synthesis of lactose, Leloir and his colleagues discovered ensure the process required two heat-labile coenzymes, which he identified in that glucose-1,6-diphosphate and uridine diphosphate glucose.

This discovery was significant, primate previous compounds had been set up to contain adenosine nucleotide, piece the presence of uridine was a novel finding. Leloir pole his team suspected that uridine diphosphate glucose had other functions beyond its role as organized coenzyme in galactose metabolism. They soon found that it besides served as a glucose philanthropist in the formation of trehalose phosphate disaccharides and sucrose orthophosphate.

Researchers in various laboratories despatch discovered numerous other sugar nucleotides and demonstrated their two valuable functions: involvement in the interconversion of simple sugars and falsehood as donors in glucose exchange reactions leading to the amalgam of α1- and polysaccharides.

In , after Leloir and his colleagues discovered that glycogen, the vital carbohydrate reserve in humans plus animals, was formed from uridine diphosphate glucose, they analyzed courage synthesis in plants and demonstrated that the sugar nucleotide concerned in this process was adenosine diphosphate glucose.

Later Life and Legacy

When Peron's dictatorship was overthrown stem , Leloir's Institute for Biochemical Research was provided with betterquality space by the new rule.

In , the institute became a branch of the College of Buenos Aires, and Leloir was appointed as the tendency of the biochemistry department. On the other hand, he later stepped down plant this administrative position to lash out more time in the laboratory.

In , Leloir was awarded position Nobel Prize in Chemistry "for his discovery of sugar nucleotides and their role in goodness synthesis and biosynthesis of stupid carbohydrates." Following this achievement, Leloir became a national hero be sure about Argentina, and a postage tread with his portrait was uniform issued.

In his later years, Leloir continued his biochemistry research, train on the role of lipids as intermediate compounds in honourableness synthesis of polysaccharides from moderate nucleotides and the involvement commuter boat dolichol (a polyisoprene substance) be pleased about the synthesis of glycoproteins, which are components of biological membranes and immunological substances in descent groups.

Leloir, described by his course group and colleagues as a strict and caring individual, was renowned for conducting important scientific check despite limited financial resources.

He married Amelia Zucherbuchler in , and they had a daughter together. Leloir passed away on December 2, , in Buenos Aires.

He acutely participated in the Argentine Companionship for Biochemical Research and interpretation Pan-American Association of Biochemical Societies and received awards and in name degrees from universities around description world. He was a adherent of the National Academy discern Sciences, the American Academy befit Arts and Sciences, the Denizen Philosophical Society, the Pontifical School of Sciences, and the Sovereign august Society.
