GPD1L

GPD1L is a biology 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 GPD1L rather than just read about it. In short: GPD1L is a human gene. The protein encoded by this gene contains a glycerol-3-phosphate dehydrogenase (NAD+) motif and shares 72% sequence identity with GPD1.

Key takeaways

GPD1L belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect GPD1L to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of GPD1L from memory before moving on to harder problems.

Reference excerpt

GPD1L is a human gene. The protein encoded by this gene contains a glycerol-3-phosphate dehydrogenase (NAD+) motif and shares 72% sequence identity with GPD1.

Structure GPD1L contains the following domains:

N-terminal – NAD+ consensus binding site a site homologous to the cardiac sodium channel SCN5A C-terminal lysine-206 residue

Tissue distribution Northern blot analysis detected a single GPD1L transcript in all tissues examined except liver. Highest expression was in heart and skeletal muscle.

Disease linkage Mutations in the GPD1L gene are associated with the Brugada syndrome and sudden infant death syndrome.

Worked examples

Example 1 — a first encounter with GPD1L

Start with the simplest possible case. Write down what GPD1L claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 GPD1L 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 GPD1L 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 GPD1L

In research: GPD1L appears in biology 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 GPD1L 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: GPD1L is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 3, Human chromosome 3 gene stubs, so understanding it makes those chapters shorter.
In everyday life: Look for GPD1L 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 GPD1L in simple terms?

GPD1L is a human gene. The protein encoded by this gene contains a glycerol-3-phosphate dehydrogenase (NAD+) motif and shares 72% sequence identity with GPD1.

Why does GPD1L matter?

Because it connects several biology 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 GPD1L?

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.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on GPD1L.
