Meaning at a glance
- Primary sense: A functional group with two sulfur atoms bonded to one another, described by the following formula: R–S–S–R'.
- Grammar: disulfide is listed as noun.
- Nearest alternatives: alcohol, anion −s–s−, chemical.
- Usage evidence: The researchers wondered if they could figure out how to capture that electrical charge as it moved across the membrane separating the fresh and salty water. They did it by creating two tiny membranes, just three atoms thick, made of molybdenum disulfide, which is plentiful and easy to produce. Then they made a tiny hole in the membranes and let osmosis take over and push the electrically charged salt ions through this nanopore.

Source and review context
This entry combines structured lexical data with WordToolSet review checks. Definitions, examples, synonyms, and usage notes may come from different source tables, so the page is designed to show evidence from more than one angle before you rely on "disulfide" in a final draft.
If a word has several senses, prefer the sense that matches your sentence's grammar and surrounding context. A correct definition can still be the wrong choice when the sentence needs a different register, emphasis, or level of specificity.
Before you rely on this definition
Read the first definition as a starting point, then check the example, synonyms, and part of speech before treating "disulfide" as the right word for your sentence.
If your draft is formal, technical, persuasive, or sensitive, compare "disulfide" with a nearby alternative so the final choice matches both meaning and reader expectation.

Definition decision workflow
1. Identify the role
Check whether "disulfide" is acting as noun in your sentence. A definition is only useful when the grammar matches the way the word is being used.
2. Test the nearest option
Compare it with "alcohol" and other nearby choices to see whether the sentence needs a softer, stronger, or more familiar word.
3. Confirm with context
Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.
Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.
Final meaning check
Before publishing a sentence with "disulfide", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.
When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.

"By analysing data from the James Webb Space Telescope, the researchers found evidence of dimethyl sulfide and dimethyl disulfide in the atmosphere of the planet known as K2-18b. The planet is 124 light-years away; one light-year is equivalent to nearly 6 trillion miles."
