Chiral molecules can be described as ones with a set of stereoisomers or left and right-handed enantiomers. As defined by Lord Kelvin, a molecule has chirality “if its image in a plane mirror, ideally realized, cannot be brought to coincide with itself.” In other words, a chiral molecule is asymmetrical in the sense that it's mirror image will not be an exact copy of itself. Chirality is key to understand in many fields such as drug development as one enantiomer of a drug may cause … Web费歇尔投影式 ( Fischer投影式 )由 赫尔曼·埃米尔·费歇尔 于1891年提出, [1] 是表示 单糖 链形结构、 氨基酸 等 有机化合物 结构的一种常用方法。 该投影式为平面结构,所有键呈竖直或水平排列,碳链纵向排列。 碳原子编号从靠近 羰基 的一端开始。 C1在最上端。 羰基 (-C =O -)位于上端,横线代表键在纸面上,竖线代表键伸进纸面。 费歇尔投影表示L- 与 D- …
