Psychosine sulfotransferase

Psychosine sulfotransferase is a engineering 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 Psychosine sulfotransferase rather than just read about it. In short: Psychosine sulfotransferase (EC 2.8.2.13) is an enzyme that catalyzes the chemical reaction: The reaction converts the cytotoxic lipid psychosine, derived from sphingosine, to a sulfate product by transferring a sulfate group from the cofactor 3'-phosphoadenosine-5'-phosphosulfate (PAPS) and giving adenosine 3',5'-bisphosphate as a byproduct. The enzyme was characterised from mouse brain.

Key takeaways

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

Reference excerpt

Psychosine sulfotransferase (EC 2.8.2.13) is an enzyme that catalyzes the chemical reaction:

The reaction converts the cytotoxic lipid psychosine, derived from sphingosine, to a sulfate product by transferring a sulfate group from the cofactor 3'-phosphoadenosine-5'-phosphosulfate (PAPS) and giving adenosine 3',5'-bisphosphate as a byproduct. The enzyme was characterised from mouse brain. This enzyme is a transferase, specifically a sulfotransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3'-phosphoadenylyl-sulfate:galactosylsphingosine sulfotransferase. Other names in common use include PAPS:psychosine sulphotransferase, and 3'-phosphoadenosine 5'-phosphosulfate-psychosine sulphotransferase.

Worked examples

Example 1 — a first encounter with Psychosine sulfotransferase

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

In research: Psychosine sulfotransferase appears in engineering 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 Psychosine sulfotransferase 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: Psychosine sulfotransferase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 2.8.2, Enzymes of unknown structure, Transferase stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Psychosine sulfotransferase 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.
