What is Acetylcholinesterase? See more. ACHE is thought to be involved in the pathology of Alzheimer's disease (AD) by accelerating the assembly of Abeta peptides into fibrillar species through forming complexes with Abeta via the peripheral anionic site on ACHE. Die Acetylcholinesterase (AChE) ist ein Enzym aus der Gruppe der Cholinesterasen, welches spezifisch den Neurotransmitter Acetylcholin (ACh) in Essigsäure (das Acetat wird nach der Spaltung rasch protoniert) und Cholin hydrolysiert.. Wirkung. Acetylcholine acts to transmit nerve impulses within the parasympathetic nervous system—i.e., that part of the autonomic nervous It acts as a neurotransmitter and conveys the nerve impulse through synaptic cleft i.e. Pseudochol deficient: Pseudocholinesterase deficiency is an inherited enzyme abnormality that results in abnormally slow breakdown of drugs such as succinylcholine (typically used during anesthesia for surgery). & ↑ ↑ ↑ ↑ Proteopedia Page Contributors and Editors (what is this?) 2-Minute Neuroscience: Acetylcholine; Toxicology of Acetylcholinesterase Inhibitors (I) - Neurotransmission; What is Acetylcholine?
