乳酸分子具有幾個(gè)對映異構體？

有2個(gè)對映異構體。

互為實(shí)物與鏡像而不可重疊的立體異構體，稱(chēng)為對映異構體 （Enantiomer，簡(jiǎn)稱(chēng)為對映體），對映異構體都有旋光性，其中一個(gè)是左旋的，一個(gè)是右旋的，所以對映異構體又稱(chēng)為旋光異構體。

1、兩個(gè)互為鏡像而不能重合的立體異構體，稱(chēng)為對映異構體，簡(jiǎn)稱(chēng)對映體。

2、對映體是指具有相同分子式的化合物中，由于原子在空間配置不同而引起的同分異構現象。

3、互為旋光異構體的兩種化合物，由于其中一個(gè)不對稱(chēng)碳原子的取代基在空間上取向不同而互成物體與鏡像的關(guān)系，并且兩者在空間上不能重疊，它們被稱(chēng)為對映體。

乳酸分子具有幾個(gè)對映異構體？

乳酸分子有兩種對映異構體。

即同一有機化合物可能有不同的對映異構體。
