|March 13, 1970
Summary
Wax esters are key energy stores in copepods like Calanus helgolandicus. Nutrition significantly impacts total lipid levels and wax ester composition in these marine organisms.
Area of Science:
- Marine Biology
- Biochemistry
Background:
- Pelagic copepods are crucial components of marine food webs.
- Lipid composition in zooplankton is vital for energy storage and survival.
Purpose of the Study:
- To investigate the role of wax esters as major lipid constituents in copepods.
- To determine how nutritional changes affect lipid content and wax ester profiles in Calanus helgolandicus.
Main Methods:
- Analysis of lipid constituents in Calanus helgolandicus and Gaussia princeps.
- Controlled laboratory experiments varying diatom diet for Calanus helgolandicus.
Main Results:
- Wax esters (C28-C44) were identified as major lipids in both species.
- Dietary quantity and type influenced total lipid accumulation and wax ester composition in Calanus helgolandicus.
Conclusions:
- Wax esters function as a significant energy reserve in Calanus helgolandicus.
- Nutritional status directly modulates lipid metabolism and storage in pelagic copepods.

01:20Carboxylic Acids to Esters: Acid-Catalyzed (Fischer) Esterification Overview
The Fischer esterification reaction was developed by the German chemist Emil Fischer in 1895. It is a condensation reaction between carboxylic acids and alcohols in an acidic medium to give esters and water.
01:25Esters to Carboxylic Acids: Saponification
Esters can be hydrolyzed to carboxylic acids under acidic or basic conditions. Base-promoted hydrolysis of esters is a nucleophilic acyl substitution reaction in which esters react with an aqueous base, followed by an acid to give carboxylic acids. This reaction is also known as saponification because it forms the basis for making soaps from fats.
The reaction requires a base in stoichiometric amounts, which participates in the reaction and is not regenerated later. So, the base acts as a...

01:13Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
Hydrolysis of esters under acidic conditions proceeds through a nucleophilic acyl substitution. In the presence of excess water, the reaction proceeds in a reversible manner, forming carboxylic acids and alcohols.
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...

01:24Esters to β-Ketoesters: Claisen Condensation Overview
Regular Claisen condensation is a base-promoted reaction involving identical esters with two α hydrogens, condensing to produce β-ketoesters. It is a nucleophilic acyl substitution reaction wherein one of the ester molecules, upon deprotonation by the base, forms a nucleophilic enolate ion, while the other molecule serves as an electrophile.
01:13Carboxylic Acids to Esters: Acid-Catalyzed (Fischer) Esterification Mechanism
Carboxylic acids react with alcohols to yield esters via an acid-catalyzed condensation reaction called Fischer esterification. This is a nucleophilic acyl substitution reaction that proceeds via a tetrahedral intermediate, where a water molecule is eliminated as the leaving group.
01:30Marine Microbial Ecology
Marine microbial ecosystems are shaped by distinct physicochemical limits, including high salinity, low nutrient availability, and fluctuating oxygen levels. These conditions favor smaller microbial cell sizes, which maximize their surface-to-volume ratio for efficient nutrient uptake.Microbial activity and community composition are closely linked to biogeochemical cycles, particularly in dynamic environments like estuaries, where halotolerant microbes thrive in response to variable salinity...
