内源性代谢物
D-Lysine produces from L-Lysine by successive chemical racemization and microbial asymmetric degradation. L-Lysine is enantiomer of D-Lysine. D-Lysine exists in all living organisms, ranging from bacteria to humans. D-Lysine is a potentially toxic compound.
可通过蛋白质与碱共热所产生的蛋白质水解液中提取或用二氢吡喃为原料进行有机合成方法生产时,所得产物才为DL-赖氨酸,实际上它是等量的D-赖氨酸分子和L-赖氨酸分子混合物,两者互为光学异构体(optical isomer)。
