Excessive doses of choline can have adverse effects. Daily 8–20 g doses of choline, for example, have been found to cause low blood pressure, nausea, diarrhea and fish-like body odor. The odor is due to trimethylamine (TMA) formed by the gut microbes from the unabsorbed choline (see trimethylaminuria). [5]
In general, the word "choline" describes the various quaternary ammonium salts containing the N,N,N-trimethylethanolammonium cation. Found in most animal tissues, choline is a primary component of the neurotransmitter acetylcholine and functions with inositol as a basic constituent of lecithin. Choline also prevents fat deposits in the liver ...
A fish-like body odor can result from extreme excess consumption of TMA precursors such as choline, carnitine and betaine (usually unobtainable via regular dietary intake, it requires high levels of supplement intake). 900mg of trimethylamine, [34] 8g-20g of choline, [35] 3g of carnitine [36] or 20g betatine [37] has been known to cause ...
Trimethylamine (TMA) is an organic compound with the formula N(CH 3) 3.It is a trimethylated derivative of ammonia.TMA is widely used in industry. [5] [6] At higher concentrations it has an ammonia-like odor, and can cause necrosis of mucous membranes on contact. [7]
This crisis may be masked by the concomitant use of atropine along with cholinesterase inhibitor medication in order to prevent side effects. Flaccid paralysis resulting from cholinergic crisis can be distinguished from myasthenia gravis by the use of the drug edrophonium (Tensilon), as it only worsens the paralysis caused by cholinergic crisis ...
Side effects include urinary retention, dry mouth, blurred vision; Glycopyrrolate: Quaternary ammonium compound; Does not cross blood-brain barrier; Hyperhidrosis. Reduce rate of sweating by blocking parasympathetic receptors in the central nervous system, smooth muscle, and sweat glands [8] First drug approved by FDA in 2018 for hyperhidrosis [11]
Acetylcholine Acetylcholinesterase Acetylcholinesterase inhibition. Acetylcholinesterase inhibitors (AChEIs) also often called cholinesterase inhibitors, [1] inhibit the enzyme acetylcholinesterase from breaking down the neurotransmitter acetylcholine into choline and acetate, [2] thereby increasing both the level and duration of action of acetylcholine in the central nervous system, autonomic ...
Choline is a necessary reagent for the synthesis of acetylcholine in the central nervous system. Neurons get their choline by specific protein transporters known as choline transporters. In the human brain microvascular endothelial cells, two systems initiate the choline absorption. The first system is known as the Choline transporter-like ...
