The impact of BCAA on the human system.

Branched chain amino acids known as BCAA (leucine, isoleucine, valine) play a variety of roles in the human body. Certainly, a rich source of BCAA are whey proteins such as isolate, hydrolyzate and whey protein concentrate (WPI, WPH, WPC). 

Scientists are discovering more and more BCAA properties, which are very poorly known to people practicing strength disciplines or endurance sports (running, triathlon, cycling, etc.) 

 

BCAA 

Inhibition of proteolysis occurs through the influence of HMB and BCKA (branched chain ketoacids, keto branched chain acids). BCAAs are transported to the brain through the same carrier that is responsible for the delivery of phenylalanine, tyrosine and tryptophan. BCAA compete with the above amino acids and have an effect on the synthesis of neutotransmitters such as dopamine, noradrenaline or serotonin (5-hydroxyl tryptamine derivative). 

BCAAs affect glucose transporters and affect insulin release. Most likely, BCAA inhibits fatigue by inhibiting serotonin production. Leucine improves insulin tolerance, however, it should be considered with BCAA supply on high-fat diets (as indicated by some observations of scientists eg Newgard et al. A branched-chain amino acid-related metabolic signature that differentiates obese and lean humans and contributes to insulin resistance.) 

 

Summary 

BCAAs perform many extremely important functions in the human body, we constantly learn about the new properties of leucine, isoleucine and valine.
