Amino acids are the main "building material" for synthesis
specific tissue proteins, enzymes, peptide hormones and other
physiologically active compounds. Part of amino acids (alanine, asparagine,
aspartic acid, glycine, glutamine, glutamic acid, proline,
serine, tyrosine, cysteine) is synthesized in the human body. This is true
called interchangeable amino acids. Other irreplaceable
amino acids (arginine, valine, histidine, isoleucine, leucine, lysine,
methionine, threonine, tryptophan, phenylalanine), are not synthesized by the body
and come in with food.
Amino acids are widely used in modern pharmacology.
Being not only structural elements of proteins and other endogenous
compounds, they are of great functional importance. Some of them
act as neurotransmitter substances (glutamine, aspartic
acids, glycine, taurine, Ag-aminobutyric acid, etc.). Phenylalanine and
tyrosine are precursors in the biosynthesis of dopamine, norepinephrine,
adrenaline tryptophan - a precursor to serotonin; histidine - pre-
histamine wreath. Derivatives of amino acids are enkephalins, endorphi
dinorphins and other neuropeptides, as well as releasing factors
(releasing factors) of the hypothalamus, pituitary hormones, etc.
Some amino acids (glutamic, Ag-aminobutyric, methionine, gly-
Qing, etc.) have found independent use as medicinal
funds. The range of new drugs synthesized is expanding.
using amino acid residues (see Dalargin, Captopril, Timogen
Of particular importance are mixtures of amino acids used as
means for parenteral nutrition.
