TLDR
Branched-chain fatty acids of the iso and anteiso series occur in many bacteria as the major acyl constituents of membrane lipids and are an important criterion used to aid identification and classification of bacteria.About:

Distribution of lipids and fatty acids in corals by their taxonomic position and presence of zooxanthellae
TL;DR: The present study highlights the importance of zooxanthellae in coral lipid metabolism, especially when compared with symbiont-host exchanges in reef-building and soft corals.
Journal ArticleDOI
Fatty acid profiles of algae mark the development and composition of harpacticoid copepods
TL;DR: The ability to elongate and desaturated FAs may reduce the importance of some FAs as diet biomarkers while it may turn the copepods into valuable trophic intermediaries in transferring organic matter from microorganisms to higher trophIC levels.

TL;DR: Data from intertidal waters, beaches and outcrops in the Bahamas and in Shark Bay in Western Australia lead us to hypothesize that ooids are colonized by a defined microbial community and that these microbes possibly mediate calcification.

Exogenous isoleucine and fatty acid shortening ensure the high content of anteiso-C15:0 fatty acid required for low-temperature growth of Listeria monocytogenes.
TL;DR: It is proposed that the anteiso precursor preferences of enzymes in the branched-chain fatty acid biosynthesis pathway ensure a high production of anteiso fatty acids, and cold-regulated chain shortening results in a further increase in anteiso-C15:0 at the expense of anteISO-C17:0.

Lipids as Universal Biomarkers of Extraterrestrial Life
TL;DR: It is made a specific recommendation that certain characteristic patterns in the composition of lipid hydrocarbons can only result from a biological process, because the signal arises from a universal requirement related to lipid bilayer fluidity and membrane stability.

Fatty acid and polar lipid composition in the classification of Cellulomonas, Oerskovia and related taxa
TL;DR: Two-dimensional thin-layer chromatography showed that almost identical and very characteristic polar lipid patterns were given by all the organisms under study: the only major components were diphosphatidylglycerol, phosph atidylinositol and two phospho-glycolipids chromatographing similarly to, but distinguishable from, the mono- and diacyl phosphatidolinositols characteristic of Nocardia and other actinomycetes.

TL;DR: The results of the present study indicate that lipid markers may be of considerable value in the classification and identification of 2, 4-diaminobutyric acid-containing phytopathogenic and saprophytic coryneform bacteria.
