Reproductive ecology of Vestimentifera (Polychaeta: Siboglinidae) from hydrothermal vents and cold seeps
… female vestimentiferans. Substantial reserves of wax esters are found in the gonad, and triacylglycerols in other tissues of the trunk. Due to the close association between the gonadal tissue and the trophosome, the only way to determine the reproductive effort in vestimentiferan tubeworms has …

Wax extraction and characterization from full-fat and defatted rice bran
Rice bran oil (RBO) contains 3-4% waxes (rice bran wax, RBW), which are composed of wax esters (WE), hydrocarbons, and other minor constituents. Saponified rice bran wax esters (RBWE) generate fatty acids, long chain alcohols, and phytosterols. Phytosterols and long chain fatty alcohols …

Changes in tear film biochemistry in end of day ocular discomfort with and without contact lenses
… sphingomyelins, phosphatidylserines, cholesterol esters, triacylglycerides, wax esters and free cholesterols did not change during the day, during CLs wear and they were not associated with CL comfort. C3 and C3a levels decreased during the day from morning to evening, implying that the classical …

Characterisation of microbial Mat communities in meltwater ponds of the McMurdo ice shelf, Antarctica
… ether-linked hydrocarbons, methylated fatty acid esters (FAME), wax esters, hopanols and sterols. Lipid biomarker profiles were similar to typical cyanobacteria dominated mats with major input from microorganisms including oxygenic and anoxygenic phototrophs, obligate aerobic and anaerobic …

The Impact of a Scleral Lens on the Eye
… samples were positively correlated to levels of wax esters (r = +0.76, P = 0.01) and hydrophobic lipids, negatively correlated to conjunctival compression (r = -0.59, P = 0.048), and not correlated to negative ocular surface health outcomes. (3) MRW thinning was not different in the test eyes …

Seabird digestive physiology in relation to foraging ecology
… vertebrates, seabirds are able to digest wax esters, compounds important in marine food webs. Procellariiforms exhibit unique gastric adaptations facilitating extended foraging trips and efficient transport of food to their young, both important advantages for predators exploiting patchy …

Lipid profiles of deep-sea organisms
… an extreme reliance on endosymbiotic bacteria. Wax esters detected are thought to be stored in oocytes. The fatty acid profile of Ridgeia piscesae reveal mainly bacterial biomarker fatty acids, but some phototrophically derived fatty acids are also present. Adult Ridgeia piscesae have no gut, so …

An investigation of the association between structural proteins and lipids with scalp hair curvature
… acyl carnitines, ceramides, endocannabinoids, wax esters, and ethyl esters) were characterised and pre-validated using multiple reaction monitoring (MRM) in separate hold-out hair samples. These lipids regulate necroptosis, as well as sphingolipid signalling and metabolism (FDR < 0.05). We …
