Jorge Allende

Jorge Allende is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Jorge Allende rather than just read about it. In short: Jorge Eduardo Allende Rivera (born 11 November 1934) is a Chilean biochemist and biophysicist known for his contributions to the understanding of proteic biosynthesis and how transfer RNA is generated, and the regulation of maturation of amphibian eggs. He has been a foreign associate of the United States National Academy of Sciences since 2001, and was awarded the Chilean National Prize for Nature Sciences (Chile)…

Reference excerpt

Jorge Eduardo Allende Rivera (born 11 November 1934) is a Chilean biochemist and biophysicist known for his contributions to the understanding of proteic biosynthesis and how transfer RNA is generated, and the regulation of maturation of amphibian eggs. He has been a foreign associate of the United States National Academy of Sciences since 2001, and was awarded the Chilean National Prize for Nature Sciences (Chile) in 1992.

Early life Jorge Allende was born in Cartago, Costa Rica, son of Octavio Allende Echeverría, Chilean Consul in the city of Puntarenas, and Amparo Rivera Ortiz, a Costa Rican artist. Because of his father's job as a diplomat, he spent his childhood years between Costa Rica, Chile and the United States. He finished high school in a Jesuit School in New Orleans, Louisiana, where his father was appointed as the Chilean Consul. Subsequently, he studied at Louisiana State University in Baton Rouge, Louisiana. He obtained the Bachelor of Science in chemistry degree in 1957.

Career He carried out his doctoral studies at Yale University in New Haven, Connecticut, United States, obtaining his Ph.D. in 1961 under the tutorship of Prof. F.M. Richards. He did post doctoral work with Prof. Fritz Lipmann at Rockefeller University and with Marshall Warren Nirenberg at NIH. During the 1960s, his research was focused on protein synthesis, a field in which he made crucial contributions. In the 1970s he was a pioneer in studying the mechanism of hormonal induction of oocyte maturation. His later research is focused in two ubiquitous protein kinases, CK1 and CK2, involved in the phosphorylation of key cellular proteins. He devoted much of his life to organizing activities for the scientific integration in Latin America especially through organizing series of training courses in molecular biology techniques, and through the creation of the Latin American Network of Biological Sciences. In recent years, Doctor Allende has been a promoter of science education through his personal commitment in several projects, like the Science Education Inquiry Based program, funded by the University of Chile, and through his participation in the Allende-Connelly Foundation, founded by him and his wife. Though he retired from active science in 2009, he remains a professor at the Faculty of Medicine. He was also Research Vice President of the University of Chile. He published his autobiography in 2010.

Personal life He married Catherine Connelly (also a biochemist) in Holyoke, Massachusetts, On September 16, 1961. He raised a family of four children: Miguel Luis, Juan Ignacio, Jorge Eduardo and Maria Amparo and has 13 grandchildren. With his wife, Catherine Connelly, he was on sabbatical at the University of California at San Diego, when the 1973 coup in Chile took place. He returned to Chile in May 1974 and was one of the main defenders of the University of Chile's autonomy, endangered by the military intervention in academic life. In December 1975 he co-signed, with other academics, a letter entitled "University under surveillance" opposing military intervention in the University of Chile. The letter was written by philosopher Jorge Millas and published in the newspaper "El Mercurio". The letter was the first appearance of a public statement by a group of academics who criticized the handling of the University of Chile by the military government.

Awards and distinctions 2007 - Recipient of the puRkwa Prize.

Worked examples

Example 1 — a first encounter with Jorge Allende

Start with the simplest possible case. Write down what Jorge Allende claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Jorge Allende before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Jorge Allende ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Jorge Allende

In research: Jorge Allende appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Jorge Allende in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Jorge Allende is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1934 births, Biochemists, Chilean biochemists, so understanding it makes those chapters shorter.
In everyday life: Look for Jorge Allende outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
