Vitamin D3 dihydroxylase

Vitamin D3 dihydroxylase is a science 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 Vitamin D3 dihydroxylase rather than just read about it. In short: Vitamin D3 dihydroxylase is a cytochrome P450 enzyme purified from the actinobacterium Streptomyces griseolus, with EC number EC 1.14.15.22 and CYP Symbol CYP105A1 (Cytochrome P450, family 105, member A1), catalyses oxidation of cholecalciferol(vitamin D3) to calcitriol.

Key takeaways

Vitamin D3 dihydroxylase belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Vitamin D3 dihydroxylase to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Vitamin D3 dihydroxylase from memory before moving on to harder problems.

Reference excerpt

Vitamin D3 dihydroxylase is a cytochrome P450 enzyme purified from the actinobacterium Streptomyces griseolus, with EC number EC 1.14.15.22 and CYP Symbol CYP105A1 (Cytochrome P450, family 105, member A1), catalyses oxidation of cholecalciferol(vitamin D3) to calcitriol.

Worked examples

Example 1 — a first encounter with Vitamin D3 dihydroxylase

Start with the simplest possible case. Write down what Vitamin D3 dihydroxylase claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Vitamin D3 dihydroxylase 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 Vitamin D3 dihydroxylase 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 Vitamin D3 dihydroxylase

In research: Vitamin D3 dihydroxylase appears in science 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 Vitamin D3 dihydroxylase 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: Vitamin D3 dihydroxylase is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cytochrome P450, EC 1.14.15, Enzyme stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Vitamin D3 dihydroxylase 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.
