Alkenones are a type of organic compound that contain a carbon-carbon double bond and a ketone group. These compounds are commonly found in marine sediments and are used as biomarkers to study past environmental conditions.
Definitions
Alkenones are a class of long-chain unsaturated ketones that are produced by certain species of algae. They are commonly used as biomarkers for paleoclimate studies because their abundance and composition can provide information about past sea surface temperatures.
Origin
The origin of alkenones can be traced back to the algae that produce them. These algae are typically found in marine environments and are able to synthesize alkenones as a way of adapting to changing environmental conditions.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, alkenones are “any of a class of unsaturated ketones that are produced by certain algae and are used as biomarkers in paleoclimate studies.” The Oxford English Dictionary defines alkenones as “a type of organic compound that contains a carbon-carbon double bond and a ketone group, commonly found in marine sediments and used as biomarkers to study past environmental conditions.”
Associations
Alkenones are commonly associated with paleoclimate studies, as they can provide information about past sea surface temperatures. They are also associated with marine sediments and certain species of algae.
Synonyms
There are no commonly used synonyms for alkenone.
Antonyms
There are no commonly used antonyms for alkenone.
The same root words
Alkenones are derived from the root words “alkene” and “ketone.” Alkenes are unsaturated hydrocarbons that contain a carbon-carbon double bond, while ketones are organic compounds that contain a carbonyl group (a carbon-oxygen double bond) bonded to two other carbon atoms.
Example Sentences
