Meaning and Definition
A nucleotide molecule that serves as the primary direct energy currency for all cellular processes.
A key organic compound involved in energy transfer within cells, formed from a guanine base attached to a ribose sugar and three phosphate groups. Its hydrolysis releases energy used to drive metabolic reactions.

Common Mistakes When Using “guanosine triphosphate”
- Misspelling as 'guanine triphosphate' (guanine is just the base, not the full nucleotide).
- Confusing its role with ATP, assuming it is the primary energy currency (ATP holds that role).
- Incorrect hyphenation: 'guanosine-triphosphate' is less standard than the open form or 'GTP'.
FAQ
Frequently Asked Questions
No. Both are nucleotide triphosphates used for cellular energy transfer, but ATP (adenosine triphosphate) is the universal primary energy currency. GTP (guanosine triphosphate) is used in more specific processes like G-protein signaling and protein synthesis.
GTP is crucial as an energy source in protein synthesis (translation) on the ribosome, as a regulator (switch) for G-proteins in signal transduction pathways, and in microtubule polymerization.
Guanosine triphosphate (GTP) has three phosphate groups and is the 'high-energy' or 'active' form. Guanosine diphosphate (GDP) has two phosphate groups and is the 'low-energy' or 'inactive' form after GTP has been hydrolysed.
Mutations in G-proteins and other GTP-binding proteins can lead to diseases like cancer. Understanding GTP cycling is key to developing drugs that target these signaling pathways.

Guanosine triphosphate is usually scientific/technical, academic in register.
Guanosine triphosphate: in British English it is pronounced /ˌɡwɑː.nə.siːn traɪˈfɒs.feɪt/, and in American English it is pronounced /ˌɡwɑː.nə.siːn traɪˈfɑːs.feɪt/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: 'G' for Guanine, 'TP' for TriPhosphate. It's the 'G' version of ATP (Adenosine Triphosphate). Just as ATP is the main energy coin, GTP is a specialised energy coin used by 'G' proteins and for 'G'rowth (protein synthesis).
Conceptual Metaphor
A charged battery for specific cellular machines (G-proteins, translation factors). A molecular switch that turns on when 'charged' with GTP and off when 'drained' to GDP.
