Trihydroxystilbene synthase

Trihydroxystilbene synthase 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 Trihydroxystilbene synthase rather than just read about it. In short: Trihydroxystilbene synthase (EC 2.3.1.95) is an enzyme that catalyzes the chemical reaction The substrates of this enzyme characterised from peanut are one unit of coumaroyl-CoA and three units of malonyl-CoA. These combine to form one unit of resveratrol, with 4 units each of coenzyme A and carbon dioxide as byproducts.

Key takeaways

Trihydroxystilbene synthase belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Trihydroxystilbene synthase to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Trihydroxystilbene synthase (EC 2.3.1.95) is an enzyme that catalyzes the chemical reaction

The substrates of this enzyme characterised from peanut are one unit of coumaroyl-CoA and three units of malonyl-CoA. These combine to form one unit of resveratrol, with 4 units each of coenzyme A and carbon dioxide as byproducts. This enzyme belongs to the family of transferases, To be specific those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is malonyl-CoA:4-coumaroyl-CoA malonyltransferase (cyclizing). Other names in common use include resveratrol synthase, and stilbene synthase. This enzyme participates in phenylpropanoid biosynthesis.

Structural studies As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes PDB: 1Z1E and PDB: 1Z1F.

Worked examples

Example 1 — a first encounter with Trihydroxystilbene synthase

Start with the simplest possible case. Write down what Trihydroxystilbene synthase 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 Trihydroxystilbene synthase 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 Trihydroxystilbene synthase 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 Trihydroxystilbene synthase

In research: Trihydroxystilbene synthase 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 Trihydroxystilbene synthase 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: Trihydroxystilbene synthase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 2.3.1, Enzymes of known structure, Hydroxycinnamic acids metabolism, so understanding it makes those chapters shorter.
In everyday life: Look for Trihydroxystilbene synthase 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.

Why does Trihydroxystilbene synthase 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 Trihydroxystilbene synthase?

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.
