Feeding of [26-13]desmosterol and [26-13C]Δ25(26)-cholesterol to cultured cells of Oryza sativa and hairy roots of Ajuga reptans var. atropurpurea followed by 13C-NMR analysis of the resulting 13C-labeled cholesteroldemonstrated that hydrogen introduction at C-25 occurs on the Si-face of desmosterol and on the Re-face of Δ25(26)-cholesterol.
将 [26-13]desmosterol 和 [26-13C]Δ25(26)-cholesterol 喂养到 Oryza sativa 和 Ajuga reptans var. atropurpurea 的毛根培养细胞中,然后对产生的 13C 标记
胆固醇进行 13C-NMR 分析,结果表明 C-25 处的氢引入发生在去脂醇的 Si 面和Δ25(26)-
胆固醇的 Re 面上。
