Tritium-labeled 14alpha-methyl-5alpha-ergost-8-enol and 5alpha-ergosta-8,14-dienol were converted to brassicasterol and poriferasterol in Ochromonas malhamensis. This indicates that the organism can rearrange these sterol structures so that they contain the naturally occurring 5(6) double bond, and suggests that O. malhamensis is able to introduce a 24(28) double bond into a nine-carbon saturated side chain which is alkylated to produce a C-29 sterol.
氚标记的14α-甲基-5α-麦角甾-8-烯醇和5α-麦角甾-8,14-二烯醇在马尔姆棕鞭藻中被转化为油菜甾醇和海绵甾醇。这表明该生物体能够重排这些甾醇结构，使其含有天然存在的5(6)双键，并表明马尔姆棕鞭藻能够将一个24(28)双键引入到一个九碳饱和侧链中，该侧链经烷基化反应生成一种C-29甾醇。
