Acetylcholine and Choline in Human Plasma and Red Blood Cells: A Gas Chromatograph Mass Spectrometriof mammalian as well as non-mammalian systems. For example the presence of ACh has been demonstrated in tissues such as spleen, liver, lung, fat, testis, kidney, pancreas and placenta of a variety of species (39, for review) in which a neurotransmitter role for ACh is not clearly evident.

Studies on the Mechanism of Action of Choline Acetyltransferasetyl CoA (AcCoA). This reaction is favored only slightly thermodynamically under physiological conditions (19), probably because ACh itself is a high-energy compound (12). It is likely that this is the case because the coulombic interaction between the trimethylammonium group and the acyloxy oxygen o

Activation of Choline Acetyltransferase by Chloride: A Possible Regulatory Mechanism regulation by mass action (14, 35); inhibition by ACh (16) and regulation by salts (27). None of these proposed mechanisms seems sufficient to explain the perfect regulation of ACh synthesis in cholinergic nerve terminals (2, 9, 10).

Even after a year we could not detect any loss of enzyme activity. As AChE is bound to synaptic membranes, only a small amount of enzyme was obtained after homogenization with conventional buf

Massoulie and Rieger initially demonstrated in . three species with sedimentation constants of 8S, 14S and 18S (19). In more recent studies Massoulie and his colleagues have observed that the predominant 18S species consists of three sets of tetrameric

If Cyclic GMP is a Neuronal Second Messenger What is the Message?ervical ganglion, the retina and the cortex (9, 18, 20, 22, 26). In the superior cervical ganglion, cGMP has been linked with the production of a slow EPSP as a consequence of cholinergic muscarinic neural transmission. In the retina, cGMP may be involved in the control of light-dark adaptation by l
