This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Glycerol-3-phosphate dehydrogenase (NAD+) rather than just read about it. In short: In enzymology, a glycerol-3-phosphate dehydrogenase (NAD+) (EC 1.1.1.8) is an enzyme that catalyzes the chemical reaction The two substrates of this enzyme are sn-glycerol 3-phosphate and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are dihydroxyacetone phosphate, the reduced cofactor NADH, and a proton.

Reference excerpt

In enzymology, a glycerol-3-phosphate dehydrogenase (NAD+) (EC 1.1.1.8) is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme are sn-glycerol 3-phosphate and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are dihydroxyacetone phosphate, the reduced cofactor NADH, and a proton. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is sn-glycerol-3-phosphate:NAD+ 2-oxidoreductase. Other names in common use include alpha-glycerol phosphate dehydrogenase (NAD+), alpha-glycerophosphate dehydrogenase (NAD+), glycerol 1-phosphate dehydrogenase, glycerol phosphate dehydrogenase (NAD+), glycerophosphate dehydrogenase (NAD+), hydroglycerophosphate dehydrogenase, L-alpha-glycerol phosphate dehydrogenase, L-alpha-glycerophosphate dehydrogenase, L-glycerol phosphate dehydrogenase, L-glycerophosphate dehydrogenase, NAD+-alpha-glycerophosphate dehydrogenase, NAD+-dependent glycerol phosphate dehydrogenase, NAD+-dependent glycerol-3-phosphate dehydrogenase, NAD+-L-glycerol-3-phosphate dehydrogenase, NAD+-linked glycerol 3-phosphate dehydrogenase, NADH-dihydroxyacetone phosphate reductase, and glycerol-3-phosphate dehydrogenase (NAD+). This enzyme participates in glycerophospholipid metabolism.

Structural studies As of late 2007, 12 structures have been solved for this class of enzymes, with PDB accession codes PDB: 1EVY, PDB: 1EVZ, PDB: 1JDJ, PDB: 1M66, PDB: 1M67, PDB: 1N1E, PDB: 1N1G, PDB: 1WPQ, PDB: 1X0V, PDB: 1X0X, PDB: 1YJ8, and PDB: 1Z82.

Worked examples

Example 1 — a first encounter with Glycerol-3-phosphate dehydrogenase (NAD+)

Start with the simplest possible case. Write down what Glycerol-3-phosphate dehydrogenase (NAD+) 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 Glycerol-3-phosphate dehydrogenase (NAD+) 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 Glycerol-3-phosphate dehydrogenase (NAD+) 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 Glycerol-3-phosphate dehydrogenase (NAD+)

In research: Glycerol-3-phosphate dehydrogenase (NAD+) 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 Glycerol-3-phosphate dehydrogenase (NAD+) 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: Glycerol-3-phosphate dehydrogenase (NAD+) is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.1.1, EC 1.1.1 stubs, Enzymes of known structure, so understanding it makes those chapters shorter.
In everyday life: Look for Glycerol-3-phosphate dehydrogenase (NAD+) 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.
