Amino Acids Deficits in Brain: Conclusion

Amino acids (AAs) are molecules containing an amine group(NH2), a carboxylic acid group(R-C=OOH)
and a side-chain( usually denoted as R) that varies between different amino acids. Amino acids
(AAs) are categorized as acidic, basic and neutral amino acids. Some amino acids are not
synthesized in the body and it is necessary to take them in diet. Such types of amino acids are called
essential amino acids (EAAs). Some amino acids are synthesized in the body and there is no needs
to take them in diet, such type of amino acids are called nonessential amino acids (NEAAs). Free
amino acids (AAs) and their metabolites are involved in many physiological functions, especially
synaptic transmission, where they serve as neurotransmitters and neuromodulators. Majority of the
neurotransmitters can influence mind-body interactions and are composed of amino acids (AAs). The
aromatic amino acids (AAAs) tryptophan (Trp), tyrosine (Tyr), and phenylalanine (Phe) are the
biosynthetic precursors for the neurotransmitters serotonin, dopamine (DA), and norepinephrine. It
has been shown that the expression levels of other amino acids (AAs), such as taurine, aspartic acid
(Asp), and glutamic acid (Glu), are higher in the brain than they are in other tissues and that these
amino acids (AAs) contribute to learning and memory processes.
