Amino acid - functions & BCAA factoids

Amino acids are the basic building blocks of protein. They are formed as a result of complete protein digestion and do the repair work involved in muscle tissue breakdown, fat burning, immunity, mood elevation, and a host of other physiological processes. There are 22 known amino acids, some non-essential (eight). Essential means the body can not manufacture them and they must be supplied via one's diet.

Branch chain amino acids are isoleucine, leucine, and valine. They assist in muscle repair immediately since they can skip digestive breakdown and are metabolized right in the muscle tissue.
