Algal lipids and effect of the environment on their biochemistry (2009, background): “... products, which can be easily catabolised to provide metabolic energy (Gurr et al. 2002) . Waxes are common extracellular surface-covering compounds but may act (in form of wax esters) as energy stores especially in organisms from cold water habitats (Guschina and Harwood 2007) . Sterols of alga”
Building the Biomarker Tree of Life (2005, background): “…steroids that have an additional alkyl substituent at position C-24 (see 7) in the side chain must still be regarded as diagnostic for eukaryotes, as no group of bacteria is known (yet) to possess the biosynthetic capacity to alkylate the steroid side chain (Brocks et al. 2003b; Volkman 2003).”
The Geological Succession of Primary Producers in the Oceans (2007, background): “A secular increase in the ratio of C28 to C29 steranes (24-methylcholestanes versus 24-ethylcholestanes), first noted by Grantham and Wakefield (1988), has been attributed to increasing production by chlorophyll c algae (which dominate C28 sterane input) relative to green algae, which synthesize pri”
Sterane biomarkers as indicators of palaeozoic algal evolution and extinction events (2006, background): “(Volkman, 1986; Patterson, 1994; Nes and Venkatramesh, 1994; Volkman et al., 1998; Volkman, 2003, 2005 ).”
Microalgae metabolites: A rich source for food and medicine (2017, background): “Microalgae produce a very wide range of phytosterols, including brassicasterol, sitosterol and stigmasterol (Patterson et al., 1994; Marshall et al., 2002; Volkman, 2003).”
Sterols and other triterpenoids: source specificity and evolution of biosynthetic pathways (2005, background): “, 2003), some species might, although the information is not compelling, but clearly most prokaryotes do not synthesize sterols (Volkman, 2003).”
The promising future of microalgae: current status, challenges, and optimization of a sustainable and renewable industry for biofuels, feed, and other products (2018, neutral): “24-Ethylcholesterol are mostly produced by cyanobacteria [182].”
Effect of diatom nutrient limitation on copepod development: role of essential lipids (2005, background): “…written consent of the publisher Mar Ecol Prog Ser 291: 125–133, 2005 composition of sterols is strongly dependent on the temperature and the spectral quality of the light source, and is usually related to the growth stage of the algae (Veron et al. 1996, Volkman 2003 and references therein).”
Role of essential lipids in copepod nutrition: no evidence for trophic upgrading of food quality by a marine ciliate (2004, methodology): “Using cyanobacterial food deficient in PUFAs as well as sterols (Volkman 2003), VonElert & Wolffrom (2001) showed that supplementation with PUFAs did not enhance the rate of growth of D. galeata, whereas recent experiments showed that sterol supplementation did enhance growth of the cladoceran…”
Algae as production systems of bioactive compounds (2015, background): “Phytosterols extracted from algae can be applied in several fields: pharmaceuticals (production of therapeutic steroids), nutraceuticals, nutrition (anticholesterol additives in functional foods and anticancer properties), and cosmetics [37, 38].”
Nutritional constraints at the cyanobacteria—Daphnia magna interface: The role of sterols (2008, background): “Cladocerans of the genus Daphnia are the dominant herbivores in lakes and ponds; owing to their abundance and their high grazing activity on the phytoplankton they provide a crucial link between primary and secondary production.”
