Glycolaldehyde dehydrogenase

Glycolaldehyde dehydrogenase 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 Glycolaldehyde dehydrogenase rather than just read about it. In short: In enzymology, glycolaldehyde dehydrogenase (EC 1.2.1.21) is an enzyme that catalyzes the chemical reaction The three substrates of this enzyme are glycolaldehyde, oxidised nicotinamide adenine dinucleotide (NAD+), and water. Its products are glycolic acid, reduced NADH, and a proton.

Key takeaways

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

Reference excerpt

In enzymology, glycolaldehyde dehydrogenase (EC 1.2.1.21) is an enzyme that catalyzes the chemical reaction

The three substrates of this enzyme are glycolaldehyde, oxidised nicotinamide adenine dinucleotide (NAD+), and water. Its products are glycolic acid, reduced NADH, and a proton. This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is glycolaldehyde:NAD+ oxidoreductase. This enzyme is also called glycol aldehyde dehydrogenase. This enzyme participates in glyoxylate and dicarboxylate metabolism.

Structural studies As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes PDB: 2HG2, PDB: 2ILU, and PDB: 2IMP.

Worked examples

Example 1 — a first encounter with Glycolaldehyde dehydrogenase

Start with the simplest possible case. Write down what Glycolaldehyde dehydrogenase 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 Glycolaldehyde dehydrogenase 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 Glycolaldehyde dehydrogenase 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 Glycolaldehyde dehydrogenase

In research: Glycolaldehyde dehydrogenase 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 Glycolaldehyde dehydrogenase 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: Glycolaldehyde dehydrogenase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.2.1, EC 1.2 stubs, Enzymes of known structure, so understanding it makes those chapters shorter.
In everyday life: Look for Glycolaldehyde dehydrogenase 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 Glycolaldehyde dehydrogenase in simple terms?

In enzymology, glycolaldehyde dehydrogenase (EC 1.2.1.21) is an enzyme that catalyzes the chemical reaction The three substrates of this enzyme are glycolaldehyde, oxidised nicotinamide adenine dinucleotide (NAD+), and water. Its products are glycolic acid, reduced NADH, and a proton.

Why does Glycolaldehyde dehydrogenase matter?

Because it connects several engineering 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 Glycolaldehyde dehydrogenase?

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.
