What are amino acids with a branch chain?

In general chemically, an amino acid with a branched chain (BCAA) is any amino acid that contains a branched carbon string connected to its alpha-e-duct atom. All amino acids contain hydrogen atom, carboxylic group and amino group, all connected to the same central carbon atom called alpha-umbrella. Alpha-carbon also carries the fourth group, commonly symbolized as a R-group; In the amino acids with a branched chain, this group R is short, in the shaped y, three-or-four hidden. The properties of this group R determine the properties of amino acids and thus its biological significance.

Once applied to biology and nutrition, the term amino acids with a branched chain (BCAAS) refers to three naturally occurring amino acids that contain small, branched, three- or four-element chain: L-leucine, L-isoleucine and L-valine. Because all naturally occurring amino acids are from the diversity of L, the prefix is ​​often dropped and commonly referred to as leucine, isolEucin and Valin. All three amino acids with branched chain are essential amino acids, which means that it is produced by the body, but must be obtained by food. However, they are common in most sources of protein, such as meat, fish, poultry and dairy products, and thus rarely shortcomings in a normal western diet.

In addition to their nutritional value in the diet, where they are vital to protein synthesis, amino acids with a branch chain are interesting as nutraceutics or foods with pharmaceutical activity, especially between athletes and biilders. It is known that leucine is important not only as part of a protein, but as a contributing muscle synthesis. It has been shown that ingestion of supplementary BCAAS increases muscle protein synthesis after training and reduces the catabolic disintegration of muscle tissue after exercise. Thus, BCAAS seems to have the ability to stimulate anabolic or protein-building, muscle reactions.

WasIt is also found that

BCAAS reduces the pain of the muscle delayed or DOMS, a sensitivity that appears several days after strenuous training. Studies found that 5 gram preschool supplement composed of isoleucine: Leusin: Valin in a 1: 2.3: 1.2 ratio has significantly reduced DOMS after intensive exercise among entities that are not for exercise. Reduced pain allegedly allows more energetic and intense exercise.

Further studies suggest that regular use of BCAA can be associated with increasing the amount of growth hormone in the blood, which could help increase muscle mass and overall body size. BCAAS also seems to reduce the levels of amino acid tryptophan in the blood. Excess tryptophan is associated with drowsiness and fatigue, so it has been suggested that this effect of BCAA decreasing tryptophan could allow longer and more strenuous exercises.

However, it should be noted that there is currently no direct evidence that BCAAs are a clear benefit even when increasing the size and amount of muscle massor when increasing athletic performance. More work is needed to establish these facts. The amino acids of the branched chain were also interesting a few years ago when pilot studies indicated that they could be effective in the treatment of symptoms of amyotrophic lateral sclerosis or Lou Gehrig's disease. Subsequent studies, however, did not confirm this, and one even suggested that the excess amino acids with a branch chain of a diet chain can even increase mortality in these patients.
