The sterols of the scallop, Patinopecten yessoensis Jay, was found to contain over 20 components. The major components were delta5-sterols, and lesser amount of ring-saturated sterols were also present. Biogenetically unusual C26 sterols (24-norcholesta-5,22-dien-3beta-ol and 24-norcholest-22-en-3beta-ol) and 24(28)-cis-24-propylidenecholest-5-en-3beta-ol (29-methylisofucosterol), 22-trans-27-nor-(24S)-24-methylcholesta-5,22-dien-3beta-ol (occelasterol), and a new sterol, 22-trans-27-nor-(24S)-24-methylcholest-22-en-3beta-ol (patinosterol), were isolated and their structures were confirmed. Occurrence of 22-trans-(24S)-24-methylcholesta-5,22-dien-3beta-ol (24-epibrassicasterol) was confirmed. 22-cis-Cholesta-5,22-dien-3beta-ol was not found.
已发现虾夷扇贝（Patinopecten yessoensis Jay）的甾醇含有20多种成分。主要成分是Δ5-甾醇，也存在少量环饱和甾醇。从生物发生角度来看不寻常的C26甾醇（24-降胆甾-5,22-二烯-3β-醇和24-降胆甾-22-烯-3β-醇）以及24(28)-顺式-24-亚丙基胆甾-5-烯-3β-醇（29-甲基异岩藻甾醇）、22-反式-27-降-(24S)-24-甲基胆甾-5,22-二烯-3β-醇（奥氏甾醇）和一种新的甾醇22-反式-27-降-(24S)-24-甲基胆甾-22-烯-3β-醇（扇贝甾醇）被分离出来，其结构得到确证。已证实存在22-反式-(24S)-24-甲基胆甾-5,22-二烯-3β-醇（24-表油菜甾醇）。未发现22-顺式胆甾-5,22-二烯-3β-醇。
