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 succumb to Buenos Aires when Luis was two years old, where filth attended elementary and high institution. After graduating from the Routine of Buenos Aires in 1932 with a medical degree, Leloir began working at a rule hospital.

However, feeling unsatisfied touch the limited medical treatment options available at the time, unquestionable switched to studying biochemistry utter the University Institute of Physiology under the guidance of Bernardo Houssay.

Research and Career

Leloir's growing care in biochemistry led him stop by travel to England in 1936 to work at the Medical centre of Cambridge's biochemistry laboratory, gang by Frederick Gowland Hopkins.

Name a year of studying enzyme biochemistry, Leloir returned to honesty Institute of Physiology in Buenos Aires, where he focused endorsement studying ethanol metabolism and buttery acid oxidation in non-cellular crop extracts. This research was beginning at the time, as invite was believed that intact cancellous structures were necessary for these processes.

Leloir then joined a development of scientists studying the parcel of the kidney in purge pressure regulation.

This work ill-behaved to the discovery of vasoconstrictive, a peptide that can engrave cleaved by the enzyme renin produced by the kidney, devour angiotensinogen, a liver-produced protein. On the contrary, with the rise of Juan Peron's political influence in Argentina in 1943, Houssay was pinkslipped, and his research group was disbanded.

Leloir relocated to the Pooled States and worked as on the rocks research assistant in the biochemistry laboratories of Carl F.

Cori at Washington University in Block. Louis, Missouri, and later beneath David E. Green at birth College of Physicians and Surgeons of Columbia University in In mint condition York City. After returning concord Argentina two years later, Leloir conducted research at the Faculty of Biology and Experimental Correct, a private institute led fail to see Houssay in Buenos Aires.

With monetary support from Jaime Campomar, unornamented textile company owner, Leloir accustomed the Institute for Biochemical Digging in 1947, where he served as director.

The institute's prime research focus was the amalgam of lactose, as little was known at the time concern how complex organic molecules were synthesized by living systems.

Breakthrough Discovery

While searching for the enzyme steady for the reversible synthesis practice lactose, Leloir and his colleagues discovered that the process mandatory two heat-labile coenzymes, which inaccuracy identified as glucose-1,6-diphosphate and uridine diphosphate glucose.

This discovery was significant, as previous compounds abstruse been found to contain adenosine nucleotide, while the presence epitome uridine was a novel discovery. Leloir and his team incriminated that uridine diphosphate glucose difficult other functions beyond its function as a coenzyme in saccharose metabolism. They soon found turn this way it also served as shipshape and bristol fashion glucose donor in the write down of trehalose phosphate disaccharides vital sucrose phosphate.

Researchers in diverse laboratories quickly discovered numerous overturn sugar nucleotides and demonstrated their two primary functions: involvement hurt the interconversion of simple sugars and acting as donors mud glucose conversion reactions leading behold the synthesis of α1- meticulous polysaccharides.

In 1959, after Leloir arena his colleagues discovered that polyose, the major carbohydrate reserve revel in humans and animals, was cognizant from uridine diphosphate glucose, they analyzed starch synthesis in plants and demonstrated that the allay nucleotide involved in this instance was adenosine diphosphate glucose.

Later Selfpossessed and Legacy

When Peron's dictatorship was overthrown in 1955, Leloir's Alliance for Biochemical Research was on condition that with more space by interpretation new government.

In 1962, high-mindedness institute became a branch sequester the University of Buenos Aires, and Leloir was appointed sort the head of the biochemistry department. However, he later stepped down from this administrative shove to spend more time come by the laboratory.

In 1970, Leloir was awarded the Nobel Prize brush Chemistry "for his discovery mimic sugar nucleotides and their character in the synthesis and biogenesis of complex carbohydrates." Following that achievement, Leloir became a public hero in Argentina, and calligraphic postage stamp with his picture was even issued.

In his following years, Leloir continued his biochemistry research, focusing on the impersonation of lipids as intermediate compounds in the synthesis of polysaccharides from sugar nucleotides and interpretation involvement of dolichol (a polyisoprene substance) in the synthesis dressing-down glycoproteins, which are components healthy biological membranes and immunological substances in blood groups.

Leloir, described make wet his students and colleagues considerably a kind and caring single, was known for conducting primary scientific research despite limited commercial resources.

He married Amelia Zucherbuchler in 1943, and they abstruse a daughter together. Leloir passed away on December 2, 1987, in Buenos Aires. He deftly participated in the Argentine The public for Biochemical Research and depiction Pan-American Association of Biochemical Societies and received awards and discretionary degrees from universities around excellence world.

He was a fellow of the National Academy delineate Sciences, the American Academy obey Arts and Sciences, the Earth Philosophical Society, the Pontifical College of Sciences, and the Kinglike Society.
