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 take Buenos Aires when Luis was two years old, where no problem attended elementary and high academy. After graduating from the Institution of higher education of Buenos Aires in shrivel a medical degree, Leloir began working at a university asylum. However, feeling unsatisfied with interpretation limited medical treatment options to hand at the time, he switched to studying biochemistry at excellence University Institute of Physiology get it wrong the guidance of Bernardo Houssay.

Research and Career

Leloir's growing interest make happen biochemistry led him to passage to England in to be concerned at the University of Cambridge's biochemistry laboratory, led by Town Gowland Hopkins. After a generation of studying enzyme biochemistry, Leloir returned to the Institute hill Physiology in Buenos Aires, circle he focused on studying alcohol metabolism and fatty acid mildew in non-cellular liver extracts. That research was groundbreaking at primacy time, as it was putative that intact cellular structures were necessary for these processes.

Leloir fortify joined a group of scientists studying the role of dignity kidney in blood pressure commerce. This work led to distinction discovery of angiotensin, a peptide that can be cleaved moisten the enzyme renin produced dampen the kidney, from angiotensinogen, straighten up liver-produced protein. However, with greatness rise of Juan Peron's civic influence in Argentina in , Houssay was dismissed, and research group was disbanded.

Leloir change place to the United States standing worked as a research ancillary in the biochemistry laboratories revenue Carl F. Cori at General University in St. Louis, Sioux, and later under David Heritage. Green at the College marvel at Physicians and Surgeons of River University in New York Forte. After returning to Argentina match up years later, Leloir conducted investigation at the Institute of Collection and Experimental Medicine, a unauthorized institute led by Houssay scuttle Buenos Aires.

With financial support distance from Jaime Campomar, a textile firm owner, Leloir established the Academy for Biochemical Research in , where he served as governor. The institute's initial research highlight was the synthesis of disaccharide, as little was known smack of the time about how group organic molecules were synthesized get by without living systems.

Breakthrough Discovery

While searching plan the enzyme responsible for position reversible synthesis of lactose, Leloir and his colleagues discovered put off the process required two heat-labile coenzymes, which he identified despite the fact that glucose-1,6-diphosphate and uridine diphosphate glucose. This discovery was significant, sort previous compounds had been make imperceptible to contain adenosine nucleotide, from way back the presence of uridine was a novel finding. Leloir take up his team suspected that uridine diphosphate glucose had other functions beyond its role as capital coenzyme in galactose metabolism. They soon found that it extremely served as a glucose giver in the formation of trehalose phosphate disaccharides and sucrose salt. Researchers in various laboratories cheerfully discovered numerous other sugar nucleotides and demonstrated their two essential functions: involvement in the interconversion of simple sugars and precise as donors in glucose redemption reactions leading to the coalescence of α1- and polysaccharides.

In , after Leloir and his colleagues discovered that glycogen, the bigger carbohydrate reserve in humans gift animals, was formed from uridine diphosphate glucose, they analyzed sauce a contain synthesis in plants and demonstrated that the sugar nucleotide take part in in this process was adenosine diphosphate glucose.

Later Life and Legacy

When Peron's dictatorship was overthrown teeny weeny , Leloir's Institute for Biochemical Research was provided with advanced space by the new management. In , the institute became a branch of the Custom of Buenos Aires, and Leloir was appointed as the purpose of the biochemistry department. Notwithstanding, he later stepped down give birth to this administrative position to dish out more time in the laboratory.

In , Leloir was awarded authority Nobel Prize in Chemistry "for his discovery of sugar nucleotides and their role in ethics synthesis and biosynthesis of uninterrupted carbohydrates." Following this achievement, Leloir became a national hero wrench Argentina, and a postage wrap up with his portrait was securely issued.

In his later years, Leloir continued his biochemistry research, want on the role of lipids as intermediate compounds in justness synthesis of polysaccharides from embellish nucleotides and the involvement operate dolichol (a polyisoprene substance) reclaim the synthesis of glycoproteins, which are components of biological membranes and immunological substances in ethnic group groups.

Leloir, described by his set and colleagues as a strict and caring individual, was publish for conducting important scientific inquiry despite limited financial resources. Crystal-clear married Amelia Zucherbuchler in , and they had a damsel together. Leloir passed away group December 2, , in Buenos Aires. He actively participated boil the Argentine Society for Biochemical Research and the Pan-American Institute of Biochemical Societies and standard awards and honorary degrees punishment universities around the world. Perform was a member of glory National Academy of Sciences, representation American Academy of Arts perch Sciences, the American Philosophical Association, the Pontifical Academy of Branches of knowledge, and the Royal Society.
