146.210 g·mol −1. Acetylcholine ( ACh) is an organic compound that functions in the brain and body of many types of animals (including humans) as a neurotransmitter. [1] Its name is derived from its chemical structure: it is an ester of acetic acid and choline. [2] Parts in the body that use or are affected by acetylcholine are referred to ...
Echocardiography, also known as cardiac ultrasound, is the use of ultrasound to examine the heart. It is a type of medical imaging, using standard ultrasound or Doppler ultrasound. [1] The visual image formed using this technique is called an echocardiogram, a cardiac echo, or simply an echo . Echocardiography is routinely used in the diagnosis ...
The enzyme cholinesterase (EC 3.1.1.8, choline esterase; systematic name acylcholine acylhydrolase) catalyses the hydrolysis of choline -based esters : an acylcholine + H 2 O = choline + a carboxylate. Several of these serve as neurotransmitters. [1] Thus, it is either of two enzymes that catalyze the hydrolysis of these cholinergic ...

Glucose-6-phosphate dehydrogenase ( G6PD or G6PDH) ( EC 1.1.1.49) is a cytosolic enzyme that catalyzes the chemical reaction. D -glucose 6-phosphate + NADP + + H2O ⇌ 6-phospho- D -glucono-1,5-lactone + NADPH + H +. This enzyme participates in the pentose phosphate pathway (see image), a metabolic pathway that supplies reducing energy to cells ...
Acetylcholinesterase ( HGNC symbol ACHE; EC 3.1.1.7; systematic name acetylcholine acetylhydrolase ), also known as AChE, AChase or acetylhydrolase, is the primary cholinesterase in the body. It is an enzyme that catalyzes the breakdown of acetylcholine and some other choline esters that function as neurotransmitters : acetylcholine + H 2 O ...
Ecotoxicology is the study of the effects of toxic chemicals on biological organisms, especially at the population, community, ecosystem, and biosphere levels. Ecotoxicology is a multidisciplinary field, which integrates toxicology and ecology . The ultimate goal of ecotoxicology is to reveal and predict the effects of pollution within the ...
