| Abstract: | The sterol composition of two sponges, Haliclona flavescens and Haliclona cinerea, from the Black Sea was investigated. Sterol composition in the two species is similar and both sponges actively transform dietary sterols into stanols and further to Δ7-sterols. Short side chain sterols of androstane and pregnane type were discovered in one sample. The composition of steryl esters and the taxonomic position of the two Haliclona species are discussed. |
