In the body, L-citrulline is converted to the amino acid L-arginine, which goes on to make another important substance nitric oxide. And nitric oxide is the secret to hard, firm, healthy erections. Heres how it worksâ¦.
Torpedo california AChE complex with acetylcholine (PDB code 2ace). Acetylcholinesterase (AChE) is key enzyme in the nervous system of animals. By rapid hydrolysis of the neurotransmitter, acetylcholine (ACh), AChE terminates neurotransmission at cholinergic synapses.It is a very fast enzyme, especially for a serine hydrolase, functioning at a rate approaching that of a diffusion-controlled reaction.Ch hydrolysis by AChE causes termination of cholinergic neurotransmission. Therefore, compounds which inhibit AChE might significantly increase the levels of ACh depleted in AD. Indeed, it was shown that AChE inhibitors improve the cognitive abilities of AD patients at early stages of the disease development.
