The Front Cover shows a variety of seleno-glycolipids being synthesized by the coupling of sugar units (in the left hand of the experimenter) and seleno-lipid units (falling with the moonlight), which work as useful detergents for X-ray structural studies of membrane proteins (in the river). A castle on the mountain flanked by a meandering river is a symbolic piece of the landscape of Gifu where these molecules have been synthesized. The moon is drawn as the allegory of selenium that was named after the Greek goddess of the moon, Selene. The authors thank Mindy Takamiya for designing the cover picture.

封面：通过硒缩醛的转缩醛化合成多种硒糖脂（Eur. J. Org. Chem. 40/2021）

封面展示了通过糖单元（在实验者的左手）和硒-脂质单元（随着月光下落）的耦合合成的各种硒-糖脂，它们可作为 X 射线结构研究的有用洗涤剂膜蛋白（在河中）。山上有一座城堡，两侧是蜿蜒的河流，是岐阜风景的象征，这些分子是在那里合成的。月亮被描绘为硒的寓言，硒以希腊月亮女神塞勒涅的名字命名。作者感谢 Mindy Takamiya 设计封面图片。更多信息可以在 N. Komura、H. Ando 等人的全文中找到。
