Of the 20 amino acids in the protiens or your bpdy, you can make alanine, arginine, assparagin ,aspartate, cysteine, glutamate, gluatamine, glycine, proline, serine and tyrosine but not histidine, isoleucine, leucine, lysine, methionine, phenylalamine, threonine, tryptophan or valine. During times of rapid growth,arginine may become essential to your diet as well, because your capacity to manufacture it might not keep up with your needs. The amino acids you are able to synthesize can come from modification of excess amino acids or from molecules produced during carbohydrate metabolism, but a lack of any of the nine essential amino acids can cause increasingly detrimental health effects if you fail to include them in your diet.
