 A lucky man
Krebs was born in Germany in 1900, the son of George Krebs, an ear, nose and throat surgeon, and his wife Alma.
Krebs was convinced that the reactions discovered by Knoop, Martius and Szent-Györgyi played a vital part in the combustion of food, because they were the only ones of the many dozens of substances investigated that burned at the same rate as food.
Krebs admitted to having been a hard task-master and poor at giving praise where it was due, but he inspired many people, including some scientists who started with him as technicians and worked their way up to become professors at other universities.

 Sir Hans Adolf Krebs (www.whonamedit.com)
Krebs served on the faculty of Oxford University from 1945 to 1967.
Among the subjects he has studied are the synthesis of urea in the mammalian liver, the synthesis of uric acid and purine bases in birds, the intermediary stages of the oxidation of foodstuffs, the mechanism of the active transport of electrolytes and the relations between cell respiration and the generation of adenosine polyphosphates.
In 1937 Krebs was able to demonstrate the existence of a cycle of chemical reactions that combines the end-product of sugar breakdown, later shown to be an «activated» form of the two-carbon acetic acid, with the four-carbon oxaloacetic acid to form citric acid.

 Hans Krebs - brief biography
Prior to Krebs discovery, experiments by T. Thunberg and F. Batelli and L.S. Stern revealed that minced animal tissues contained substances that could transfer hydrogen atoms from specific intracellular organic acids (including succinate, malate, and citrate) to methylene blue dye, reducing it to a colorless form.
Krebs discovered the formation of citrate from oxaloacetate and pyruvate, the 'missing link' that allowed the known reactions to form a cyclic sequence.
Krebs' own account of the history of the discovery of the cycle can be found in his article, The History of the Tricarboxylic Acid Cycle, Perspect.

Krebs first became interested in the process by which the body degrades amino acids.
Krebs then investigated the processes involved in the production of urea from the removed nitrogen atoms, and by 1932 he had worked out the basic steps in the urea cycle.
Krebs was born in Hildesheim and studied at the the universities of Göttingen, Freiburg, Munich, Berlin, and Hamburg.

 Hans Krebs: The Genius of Biochemistry - Brian Wijerante and Glenn Carroll Strait
Brian Wijerante knew the Krebs family, having worked with Sir Hans in the last few years of his life when Krebs was actively contributing to discussions in the areas of science, values and education.Glenn Carroll Strait is co-editor of the Natural Science section.
Regular visitors to the Krebs' residence in Iffley, Oxford, will observe, in the cozy drawing room where they were hosted, a touch of candor, of utilitarianism, and of nineteenth century German Idealism.
Sir Hans Krebs died in Oxford on 22 November 1981, at the age of eighty-one, just two weeks after he had left his beloved laboratory for hospital treatment of what he thought to be a minor stomach complaint.

 Carolina: Science Quizzes: Krebs
Krebs researched intermediate metabolism, eventually explaining how foodstuffs are oxidized to produce energy in chemical processes known as the Krebs cycle (also known as the tricarboxylic acid cycle and the citric acid cycle).
Krebs said in his acceptance speech for the Nobel Prize that he became interested in research because he was convinced that “an understanding of the process of energy production will eventually help us in solving some of the practical problems of medicine.”
Hans Adolf Krebs was born in 1900 to a well-educated professional family in Germany.

 Making Energy: Story Time - Hans Krebs
Hans Krebs was born in a medieval town in Northern Germany called Hildesheim, near Hanover (pictures are on the right).
Hans lived comfortably as a child, in a large house with a nice back yard and garden.
Hans' father believed that the only hope for Jews in Germany was to abandon their faith and become totally German.

 Making Energy: Story Time - Hans Krebs
Hans and his colleagues continued to be supported by their parents, many of whom had lost their life savings in the economic crash in Germany.
This discovery was important and it also prepared Hans' mind to accept the idea that a chemical compound could go through a series of transformations that finally led to a re-making of the original compound.
Hans knew that as a Jew he must leave his homeland because Adolph Hitler had taken over the country and was persecuting Jews.

 Helmut Krebs: The Patrician tenor/countertenor of the Second Half of Twentieth Century Europe
Krebs was born on the birthday of Heinrich Schütz: the 8th of October 1913 in Dortmund, Westfalen.
Krebs was also doing studio recordings extensively for the DG Archiv label in authentic early-music reconstructions of Lassus [at the Aachen Cathedral, under Rudolph Pohl], Prätorious, Scheidt [under Mauersberger], Eccard, Crappius, [some of the most engaging solo cantati of] Dietrich Buxtehude, and the early Italian Baroque masters such as Caccini, Cima and Viadana.

The Krebs cycle, or citric acid cycle, was put forth to account for the oxidation of carbohydrates by animal tissues.
Of course, later the acetyl derivative (a compound formed in fat degradation) was identical to the compound formed by the oxidative decarboxylation of pyruvate; thus proving that the Krebs cycle also serves for the oxidation of fats.
Krebs' later work showed that the cycle is not restricted to animals, but rather is present in nearly all aerobic cells.

 Controlled oxidation of substrates: selected Krebs cycle mechanisms
Unfortunately, such a presentation may leave students with the impression that metabolites follow a linear progression through glycolysis to acetyl-coenzyme A to citric acid, through the Krebs intermediates to oxaloacetate, which is then coupled to the two carbons of another acteyl-coenzyme A to regenerate citric acid.
They must be replaced in order to maintain energy balance, however the fate of a Krebs intermediate is not necessarily to cycle through the enzymes until it is completely oxidized to carbon dioxide and water.
The succinate dehydrogenase complex is also known as complex II of the electron transport system, thus the oxidation of succinate to fumarate is the only Krebs reaction that takes place on the inner membrane itself, as opposed to the other reactions that are catalyzed by soluble enzymes.

 OUP: Hans Krebs: Holmes   (Site not responding. Last check: 2007-10-08)
This comprehensive volume completes Frederic Holmes's notable and detailed biography of Hans Krebs, from the investigator's early development through the major phase of his groundbreaking investigation, which lay the foundations upon which the modern structure of intermediary metabolism is built.
With access to Krebs's research notebooks as well as to Krebs himself through more than five years of personal interviews, the author provides an insightful analysis of Hans Krebs and of the scientific process as a whole.
This second volume reconstructs the investigative pathway and the professional and personal life of Hans Krebs, from the time of his arrival in England in 1933 until 1937, when he made the discovery for which he is best known--the formulation of the citric acid cycle.

 Biographical Sketches
He introduced the controversial "~" symbol to indicate a "high-energy" phosphate bond, representing for example ATP as ADP~P. It was not for this work, however, that Lipmann shared the 1953 Nobel Prize in Physiology or Medicine with Hans Krebs but for his discovery in 1947 of coenzyme A and its importance for intermediary metabolism.
He also showed that the two-carbon compound in the Krebs cycle that joined with oxaloacetic acid to form citric acid was in fact acetyl CoA.
The coenzyme was soon shown to have wider applications than the Krebs cycle, when in 1950 Feodor Lynen found that it played a key role in the metabolism of fats.

 Cayman Turtle Farm - Scientific papers- Remarks on Professor Sire Hans Krebs
I say that by way of explanation that my memories of Sir Hans cover only a short space of time from the mid- to late 1930's and of the Sheffield Laboratory only, and it is unfortunate that 40 years have dimmed the capacity for total recall.
Fortunately Sir Hans was out at the time and we had a chance to straighten up the lab before his return.
It was only some time later when I went into industry that I learned that mercury at ambient temperatures has sufficient vapor pressure to be extremely toxic and for some time I was haunted by the thought of Sir Hans standing in the lab with the possibility of large globules of mercury under the floorboards.
