Tito Ureta
Tito Ureta Aravena (1935–2012) was a Chilean biochemist, known for studies of hexokinases in many organisms. Personal life Tito Ureta was born on 10 October 1935 in Iquique, Chile, where he was educated at the Domingo Santa María School, and in the Liceo José Victorino Lastarria (Santiago). He married Sara Elfriede Herbstaedt Yáñez. Education and early research Ureta's first university studies at the University of Chile were in medicine, and he qualified as a surgeon in 1963. However, his interest turned to biochemistry and he devoted his career to research and experimental work, on hexokinases in particular. In 1960 he joined the group of Hermann Niemeyer, with whom he obtained his doctorate on the basis of a thesis on the purification and characterization of the enzyme responsible for phosphorylation of glucose in the mammalian liver. He completed his training in a post-doctoral period in the laboratory of Fritz Lipmann at the Rockefeller University in New York. ...

Iquique
Iquique () is a port List of cities in Chile, city and Communes of Chile, commune in northern Chile, capital of both the Iquique Province and Tarapacá Region. It lies on the Pacific coast, west of the Pampa del Tamarugal, which is part of the Atacama Desert. It has a population of 191,468 according to the 2017 census. It is also the main commune of Greater Iquique. The city developed during the heyday of the Potassium nitrate, saltpetre mining in the Atacama Desert in the 19th century. Once a Peruvian city with a large Chilean population, it was conquered by Chile in the War of the Pacific (1879–1883). Today it is one of only two free ports of Chile, the other one being Punta Arenas, in the country's far south. History Although the city was founded in the 16th century, there is evidence of habitation in the area by the Changos, Chango people as early as 7,000 BC. During colonial times, Iquique was part of the Viceroyalty of Peru as much of South America was at the time, and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humberto Maturana
Humberto Maturana Romesín (September 14, 1928 – May 6, 2021) was a Chilean biologist and philosopher. Some name him a second-order cybernetics theoretician alongside the likes of Heinz von Foerster, Gordon Pask, Herbert Brün and Ernst von Glasersfeld. Maturana, along with Francisco Varela and Ricardo B. Uribe, was known for creating the term "autopoiesis" about the self-generating, self-maintaining structure in living systems, and concepts such as structural determinism and structural coupling. His work was influential in many fields, mainly the field of systems thinking and cybernetics. Overall, his work is concerned with the biology of cognition.Magnus Ramage, Karen Shipp (2012) ''Systems Thinkers'' Maturana (2002) insisted that autopoiesis exists only in the molecular domain, and he did not agree with the extension into sociology and other fields: The molecular domain is the only domain of entities that through their interactions give rise to an open ended dive ...

Glycogen Synthesis
Glycogenesis is the process of glycogen synthesis or the process of converting glucose into glycogen in which glucose molecules are added to chains of glycogen for storage. This process is activated during rest periods following the Cori cycle, in the liver, and also activated by insulin in response to high glucose levels. Steps * Glucose is converted into glucose 6-phosphate by the action of glucokinase or hexokinase with conversion of ATP to ADP. * Glucose-6-phosphate is converted into glucose-1-phosphate by the action of phosphoglucomutase, passing through the obligatory intermediate glucose-1,6-bisphosphate. * Glucose-1-phosphate is converted into UDP-glucose by the action of the enzyme UDP-glucose pyrophosphorylase. Pyrophosphate is formed, which is later hydrolysed by pyrophosphatase into two phosphate molecules. * The enzyme glycogenin is needed to create initial short glycogen chains, which are then lengthened and branched by the other enzymes of glycogenesis.
