MetaboLights

MetaboLights 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 MetaboLights rather than just read about it. In short: MetaboLights is a data repository founded in 2012 for cross-species and cross-platform metabolomic studies that provides primary research data and meta data for metabolomic studies as well as a knowledge base for properties of individual metabolites. The database is maintained by the European Bioinformatics Institute (EMBL-EBI) and the development is funded by Biotechnology and Biological Sciences Research Council (…

Key takeaways

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

Reference excerpt

MetaboLights is a data repository founded in 2012 for cross-species and cross-platform metabolomic studies that provides primary research data and meta data for metabolomic studies as well as a knowledge base for properties of individual metabolites. The database is maintained by the European Bioinformatics Institute (EMBL-EBI) and the development is funded by Biotechnology and Biological Sciences Research Council (BBSRC). As of July 2018, the MetaboLights browse functionality consists of 383 studies, two analytical platforms, NMR spectroscopy and mass spectrometry. Semantic annotation is based on various ontologies and controlled vocabularies, including the BRENDA tissue ontology and the NCBI taxonomy. The metabolite structure data is linked to chemical databases, including ChemSpider, PubChem, and ChEBI. Links to metabolite databases, however, seem to be missing. MetaboLights consists of two components:

a repository, that enables the metabolomic community to share experimental findings, data and protocols for any metabolomic study. (Fig. 1-2)

a reference layer of individual metabolite compounds and their reference spectra including additional information on their biological roles, locations, concentrations and raw data from metabolomic experiments. (Fig. 3)

Scope and access The data stored in MetaboLights is available for download from an FTP site and can be reused by the scientific community, where data sharing is considered an integral part of the scientific method. Copyright and license information, however, is not easily identifiable. MetaboLights includes user tools for submission of experiments using the ISA-TAB format for metadata tagging of all submissions. Submitted studies are automatically assigned a stable unique accession number (e.g. MTBLS1) that can be used as a publication reference; MetaboLights is one of the repositories recommended by several scientific journals, including EMBO Journal and Nature's Scientific Data. There is also a guided submission process to help meet the Metabolomics Standards Initiative (MSI) recommendations for high quality data submissions for NMR and MS experiments.

Worked examples

Example 1 — a first encounter with MetaboLights

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

In research: MetaboLights 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 MetaboLights 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: MetaboLights is common in secondary-school and first-year university syllabi. It links to neighbouring topics Metabolomic databases, Science and technology in Cambridgeshire, South Cambridgeshire District, so understanding it makes those chapters shorter.
In everyday life: Look for MetaboLights 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 MetaboLights in simple terms?

Why does MetaboLights matter?

Because it connects several science 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 MetaboLights?

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.
