| Description | Brassicasterol belongs to the class of organic compounds known as ergosterols and derivatives. These are steroids containing ergosta-5,7,22-trien-3beta-ol or a derivative thereof, which is based on the 3beta-hydroxylated ergostane skeleton. Thus, brassicasterol is considered to be a sterol lipid molecule. Its relatively high concentration and stability allows it to be used in the assessment of the origin of organic matter in samples, especially sediments. Brassicasterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, brassicasterol is found, on average, in the highest concentration in common walnuts. Brassicasterol has also been detected, but not quantified in, several different foods, such as pecan nuts, pepper (c. Frutescens), redcurrants, alfalfa, and leeks. This could make brassicasterol a potential biomarker for the consumption of these foods. A list of the algae in which brassicasterol has been identified is shown below together with approximate composition. However, the cholesterol behaves in a similar manner, and the ratio brassicasterol/cholesterol is fairly uniform at all depths, indicating either a comparable degradation rate with no change in source or different degradation rates and a change in source. This means that, in most environmental systems, brassicasterol will be associated with the solid phase. The free sterols are then separated from the polar lipids by partitioning into a less polar solvent (e.G, hexane). (1r,3as,3bs,7s,9ar,9bs,11ar)-1-[(2r,3e,5s)-5,6-dimethylhept-3-en-2-yl]-9a,11a-dimethyl-1h,2h,3h,3ah,3bh,4h,6h,7h,8h,9h,9bh,10h,11h-cyclopenta[a]phenanthren-7-ol is found in Alitta succinea, Aplysina fistularis, Aureoumbra lagunensis, Axinella aruensis, Axinella cannabina, Baccharoides anthelmintica, Brassica juncea, Bugula neritina, Cymodocea nodosa, Dicrateria inornata, Diplopterygium glaucum, Dragmacidon lunaecharta, Echinometra lucunter, Haliclona oculata, Hydrodictyon reticulatum, Kalanchoe petitiana, Mikania campanulata, Nervilia plicata, Petrosia weinbergi, Phallusia nigra, Chrysotila lamellosa, Tuber melanosporum and Verongula gigantea.
