A branched-chain amino acid (BCAA) is an amino acid having aliphatic side-chains with a branch (a central carbon atom bound to three or more carbon atoms). Among the proteinogenic amino acids, there are three BCAAs: leucine, isoleucine and valine.Non-proteinogenic BCAAs include norvaline and 2-aminoisobutyric acid.
The three proteinogenic BCAAs are among the nine essential amino acids for humans, accounting for 35% of the essential amino acids in muscle proteins and 40% of the preformed amino acids required by mammals.
Musle Supplement--BCAA:
On the role of health supplements in fitness,We don't care before, But when we useing a month we will be exciting because of the effect,Successful fitness need hard exercise but also scientific diet and important nutrition supplement.
In recent years, branched-chain amino acid supplements have come back into vogue in the bodybuilding and fitness community, and with good reason. There's more research that supports the use of BCAAs than most other supplements on the market.
While BCAA supplementation may be useful for gaining mass, I believe BCAAs are especially helpful for maintaining muscle mass while on a calorie-deficit diet. They're particularly useful for bodybuilding competitors who take their physiques to the lean extreme.
Although dieting down makes you look awesome onstage, on the beach, and to your friends of the opposite sex, it can also take a chunk out of your muscle mass.
How do you defend against this three-headed monster of muscle loss? Attack all three heads!
It's well established that branched-chain amino acids (particularly leucine) stimulate protein synthesis, and might do so to a greater extent than a normal protein on its own. BCAAs also increase synthesis of the cellular machinery responsible for carrying out the process of protein synthesis. したがって, BCAAs not only increase the rate of protein synthesis, but they also increase the cell's capacity for protein synthesis! Yep, you read that right.
BCAAs also work in your favor by reducing the rate of protein breakdown. They do this (primarily) by decreasing the activity of the components of the protein breakdown pathway, and also by decreasing the expression of several complexes involved in protein breakdown. (In this case, they decrease the amount of mRNA produced from the gene that codes for these components.)
If we revisit our original equation for muscle mass, it's plain to see that increasing synthesis and decreasing breakdown will equate to muscle gain/maintenance. And that, my friends, is how we fight the Cerberus of muscle loss
