The other major biological action of glycoalkaloid is the inhibition of acetylcholine esterase(아세틸콜린 에스터레이스), the enzyme involved in the hydrolysis of the neurotransmitter acetylcholine at the cholinergic synapses. The antiacetylcholine esterase activity of glycoalkaloids is manifested by neurological symptoms such as weakness, confusion and depression.
