Leslie Dutton

Leslie Dutton is a astronomy 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 Leslie Dutton rather than just read about it. In short: Peter Leslie Dutton FRS is a British biochemist, and Eldridge Reeves Johnson Professor of Biochemistry and Biophysics in the Perelman School of Medicine at the University of Pennsylvania. He is a 2013 recipient of the John Scott Award for his work on electron transfer, studying the organization of electrons in cells and the mechanisms by which they convert light or oxygen into energy for the cell.

Key takeaways

Leslie Dutton belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Leslie Dutton to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Leslie Dutton from memory before moving on to harder problems.

Reference excerpt

Peter Leslie Dutton FRS is a British biochemist, and Eldridge Reeves Johnson Professor of Biochemistry and Biophysics in the Perelman School of Medicine at the University of Pennsylvania. He is a 2013 recipient of the John Scott Award for his work on electron transfer, studying the organization of electrons in cells and the mechanisms by which they convert light or oxygen into energy for the cell.

Education Leslie Dutton was born in England. He received a B.Sc. (Honors) in Chemistry at the University of Wales in 1963, and a Ph.D. in Biochemistry at the University of Wales in 1967.

Research In 1968, Leslie Dutton joined the University of Pennsylvania, where he now leads the Dutton lab at the Perelman School of Medicine. He is also Principal Investigator at the Photosynthetic Antenna Research Center. Dr. Dutton attempts to understand elementary processes of oxidation-reduction and related biological events. Natural enzymes called oxidoreductases are involved in biological functions including gene regulation, signalling, long range electron transfer, energy conversion (in photosynthesis and respiration), atom transport, drug detoxification, and enzyme catalysis. Using physical, chemical and computational methods, the Dutton lab studies oxidoreductases and redox proteins to discover mechanisms of electron transfer over large distances through proteins and understand quantum mechanical electron tunneling theory. Understanding electron tunnelling gives scientists a foundation for investigation of biological redox reactions and their relationship to chemical events such as proton exchange, protein conformation, and energy conversion. Through their understanding of such processes, Dutton and his lab have been able to manipulate electron transfer in structured highly simplified settings, and create man-made versions of proteins. Such maquettes, simple versions of their highly complex biological counterparts, enable researchers to model the minimal requirements for function. Futuristic applications could include creation of clean energy sources and prevention of genetic and age-related diseases.

Worked examples

Example 1 — a first encounter with Leslie Dutton

Start with the simplest possible case. Write down what Leslie Dutton claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Leslie Dutton 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 Leslie Dutton 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 Leslie Dutton

In research: Leslie Dutton appears in astronomy 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 Leslie Dutton 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: Leslie Dutton is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alumni of the University of Wales, British biochemists, British biophysicists, so understanding it makes those chapters shorter.
In everyday life: Look for Leslie Dutton 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.
