Arachidonoyl coenzyme A lithium is an unsaturated fatty acyl coenzyme A, formed by the condensation of the thiol group of coenzyme A with the carboxyl group of arachidonic acid[1].
Arachidonoyl coenzyme A lithium is different of its synthetic activity in different regions, with higher synthesis in the homogenate and microsomes than in the cerebellum and brainstem while lower synthesis in the synaptic plasma membrane, and is unaltered in bicuculline-induced status epilepticus in male Wistar rats[1].
