A branched-chain amino acid (BCAA) is a complex of three essential amino acids leucine (1.355 g), isoleucine (0.807 g) and valine (0.831 g). Soy beans contain 2.993 grams of BCAAs per every 100 grams.
Creatine can be synthesized in the body from the three common amino acids glycine (0.770 g), arginine (1.291 g) and methionine (0.224 g). Soy beans contain 2.285 grams of these amino acids per every 100 grams.
