Sterols, free fatty acids, and total fatty acid content in the massive Porites spp. corals cultured under different pCO 2 and temperature treatments
Lipids may serve as energy reserves to support coral calcification, allow acclimation to higher temperatures, and are implicated in the control of CaCO 3 precipitation. Here, we report the lipid composition of the soft tissues (including host and symbionts) of 7 massive Porites spp. coral colonies (...

Lipids may serve as energy reserves to support coral calcification, allow acclimation to higher temperatures, and are implicated in the control of CaCO 3 precipitation.

We report the fatty acid methyl esters (FAME), free fatty acid (FFA) to total fatty acid content, sterol and wax ester profiles, and identify two ketones ( n -alkanone) and three long chain aldehyde ( n -alkanal) derivatives.
