Rocaglamide

Rocaglamide 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 Rocaglamide rather than just read about it. In short: Rocaglamide is a natural product which belongs to a class of molecules called flavaglines. This compound was isolated in 1982 by Ming-Lu King (金明儒) and colleagues based on its antileukemic activity.

Key takeaways

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

Reference excerpt

Rocaglamide is a natural product which belongs to a class of molecules called flavaglines. This compound was isolated in 1982 by Ming-Lu King (金明儒) and colleagues based on its antileukemic activity. The name of Rocaglamide is named from two parts: Roc- and aglamide. Roc- means Republic of China (中華民國), where this product was first isolated; aglamide indicates this product is isolated from Large-leaved Aglaia (Scientific name: Aglaia rimosa). Like other flavaglines, rocaglamide displays potent insecticidal, antifungal, anti-inflammatory and anticancer activities. Rocaglamide A (RocA) inhibits eukaryotic translation initiation by binding to the translation initiation factor eIF4A and converting it into a translational repressor. Rocaglamide was first synthesized by Barry Trost in 1990. Although other syntheses have been described since, Trost’s remains the only one to afford rocaglamide in an enantio-specific manner.

Worked examples

Example 1 — a first encounter with Rocaglamide

Start with the simplest possible case. Write down what Rocaglamide 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 Rocaglamide 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 Rocaglamide 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 Rocaglamide

In research: Rocaglamide 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 Rocaglamide 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: Rocaglamide is common in secondary-school and first-year university syllabi. It links to neighbouring topics Carboxamides, Organic compound stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Rocaglamide 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.

Frequently asked questions

What is Rocaglamide in simple terms?

Why does Rocaglamide matter?

Because it connects several chemistry ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Rocaglamide?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
