carbanion：碳负离子

正文 碳负离子(Carbanion)指的是含有一个连有三个基团,并且带有一对孤对电子的碳的活性中间体. 碳负离子带有一个单位负电荷,通常是四面体构型,其中孤对电子占一个 sp3 杂化轨道. 通过比较相应酸的酸性大小,可以大致判断碳负离子的稳定性大小.

carbanion：碳阴离子

(2) 与PPP途径中非氧化性途径的转醛脢 (transaldolase) 有关;形成胺基酸与PLP结合的中间物(为稳定此Schiff base,常形成碳阴离子 (carbanion)的中间物);胺基酸的消旋作用 (racemization)是催化胺基酸D-form与L-form间的镜像异构作用.
