An amino acid neurotransmitter is an amino acid which is able to transmit a nerve message across a synapse. Neurotransmitters (chemicals) are packaged into vesicles that cluster beneath the axon terminal membrane on the presynaptic side of a synapse in a process called endocytosis .
A study performed in 2015 with vervet monkeys (Chlorocebus sabaeus) in St. Kitts, which are homozygous for the apoE4 gene (a condition which in humans is a risk factor for Alzheimer's disease), found that vervets that were administered BMAA orally developed hallmark histopathology features of Alzheimer's disease, including amyloid beta plaques and neurofibrillary tangle accumulation.
Phenethylamine is a primary amine, the amino-group being attached to a benzene ring through a two-carbon, or ethyl group. [10] It is a colourless liquid at room temperature that has a fishy odor, and is soluble in water, ethanol and ether . [ 10 ]
The human eye is a wondrous thing. It is considered the body’s most complex organ after the brain and contains over 2 million working parts. About 80% of all learning happens through vision.
Citrullination is distinct from the formation of the free amino acid citrulline as part of the urea cycle or as a byproduct of enzymes of the nitric oxide synthase family. Enzymes called arginine deiminases (ADIs) catalyze the deimination of free arginine, while protein arginine deiminases or peptidylarginine deiminases (PADs) replace the ...

Most proteins and peptides contain both alcohols and amino groups. Two amino acids are alkanolamines, formally speaking: serine and hydroxyproline. Veratridine and veratrine; Tropane alkaloids such as atropine; hormones and neurotransmitters epinephrine (adrenaline) and norepinephrine (noradrenaline)
Codon–amino acids mappings may be the biological information system at the primordial origin of life on Earth. [122] While amino acids and consequently simple peptides must have formed under different experimentally probed geochemical scenarios, the transition from an abiotic world to the first life forms is to a large extent still unresolved ...
