amino acid neurotransmitter : ウィキペディア英語版 | amino acid neurotransmitter An amino acid neurotransmitter is an amino acid which is able to transmit a nerve message across a synapse. Neurotransmitters (chemicals) are packaged into vesicles that cluster beneath the axon terminal membrane on the presynaptic side of a synapse in a process called endocytosis.〔 〕 Amino acid neurotransmitter release (exocytosis) is dependent upon calcium Ca2+ and is a presynaptic response. There are inhibitory amino acids (IAA) or excitatory amino acids (EAA). Some EAA are L-Glutamate, L-Aspartate, L-Cysteine, and L-Homocysteine.〔 These neurotransmitter systems will activate post-synaptic cells.〔 〕 Some IAA include GABA, Glycine, β-Alanine, and Taurine.〔 〕 The IAA depress the activity of post-synaptic cells.〔 ==See also==
