Amino acids are structural units of proteins. There are 22 amino acids that make up proteins.
The test for amino acids includes the following amino acids: alanine, alpha-aminobutyric acid, arginine, asparagine, aspartic acid, carnosine, citrulline, cysteine, glutamine, glutamic acid, glycine, histidine, histidine, histidine, liquefaction Proline, sarcosine, serine, taurine, threonine, tryptophan, tyrosine, valine.
Amino acids should be tested in the following cases:
High levels of plasma amino acids indicate a congenital metabolic disorder of this amino acid; The results should be interpreted in parallel with the result obtained in the determination of amino acids in urine.
In healthy people, the source of amino acids is protein obtained from food. Although most amino acids are produced in the body, there are several amino acids that are not synthesized by mammals and are therefore considered essential amino acids that ensure normal growth and maintenance of health.
Gastrointestinal proteolytic enzymes destroy food-derived proteins and secrete amino acids that are absorbed in the small intestine and that are involved in the body's supply of amino acids. Liver and other tissues use this supply for the synthesis of plasma and intracellular proteins.
Amino acids in the blood are filtered into the renal glomeruli but are usually reabsorbed at the tubular level. Therefore, high levels of amino acids in the blood are accompanied by increased elimination of amino acids by the kidneys. Increases in amino acid levels in healthy people are transient and are associated with excessive amounts of protein in the diet.
Increased levels of amino acids in plasma may indicate inherited disorders of amino acid metabolism.
The best sample for determining most amino acids is plasma. Determining the level of amino acids in the urine is especially helpful if a specific disorder is affecting the renal transport system.
For babies: Do not eat small food for 4 hours before taking the test material.
It is recommended to follow a normal diet for 2-3 days before the study.
Prior to the study, consult your doctor about discontinuing the medication you are taking.
