TLDR
The marine siphonous green alga, Codium fragile, was shown to contain two 25-methylene sterols, which were identified as (24 S )-24-ethylcholesta-5,25-dien-3β-ol and the previously unknown (24S )- 24-methylcholeste- 5, 25-diens-3 β-ol for which the trivial name codisterol is proposed.About:

Marine natural products.
TL;DR: This review covers the literature published in 2014 for marine natural products, with 1116 citations referring to compounds isolated from marine microorganisms and phytoplankton, green, brown and red algae, sponges, cnidarians, bryozoans, molluscs, tunicates, echinoderms, mangroves and other intertidal plants and microorganisms.

Biochemical composition of three algal species proposed as food for captive freshwater mussels
Catherine M. Gatenby,David M. Orcutt,Daniel A. Kreeger,Bruce C. Parker,Vannessa A. Jones,Richard J. Neves +5 more
TL;DR: To identify potential diets for rearing captive freshwater mussels, the protein, carbohydrate, and lipid contents of two green algae, Neochloris oleoabundans, Bracteacoccus grandis, and one diatom, Phaeodactylum tricornutum, were compared at different growth stages.

Changes in plant lipids during passage through the gut of Calanus
TL;DR: Comparison of the lipid data for faecal pellets with those for the plant showed that marked changes to dietary lipids occur during passage through the gut of the copepod, illuminating the fate of specific dietarylipids in Calanus and the contributionCopepod faecic pellets can make to the overall lipid composition of bottom sediment in many marine environments.

The phylogenetic distribution of sterols in tracheophytes

TL;DR: The sterols of nine mature plant species in seven families ranging from the subphylum Lycopsida through the Filicopsida and the classes Gymnospermae and Angiospermaes in the Pteropsida were structurally and stereochemically defined and lead logically to the conclusion that the 24α-alkyl structure, especially 24-α-ethyl-Δ5-sterols (sitosterol and the much rarer stigmasterol) constitutes the

Sterols of Leishmania species. Implications for biosynthesis
TL;DR: Lanosterol and 4,4-dimethylcholesta-8,24-dien-3 beta-ol were detected in all species studied, and squalene was identified in a stock of L. tropica.

The distribution of sterols in algae
TL;DR: Gas and thin layer chromatography and mass spectroscopy in particular, have been used to resolve some of the confusion concerning the sterol composition of algae.

A consideration of the evolutionary and taxonomic significance of some biochemical, micromorphology, and physiological characters in the thallophytes.
TL;DR: The phylogeny of organisms in the divisions and classes of the thallophytes as suggested by chemical, micromorphological, functional, and life cycle criteria is discussed.

NMR spectra of C-24 isomeric sterols
TL;DR: In this article, the NMR spectra of four pairs of C-24 isomeric sterols, Campesterol, 22,23-dihydrobrassicasterol, α-spinasterol-chondrillasterol and stigmasterol-poriferasterol were studied by NMR-based spectroscopy and their spectra were presented.

The identification of 28-isofucosterol in the marine green algae Enteromorpha intestinalis and Ulva lactuca
TL;DR: The major sterol of Enteromorpha intestinalis and Ulva lactuca has been identified as 28-isofucosterol as discussed by the authors, and gas-liquid chromatography has indicated the presence of cycloartenol and 24-methylene cycloartanol in both algae and 24ethylidene lophenol in E. intestinalis.
