Sorts of Acids and Human Organism
Monday, March 1st, 2010Human beings use twenty amino acids for their purposes, but there are approximately 240 of them in nature. Humans divide those amino acids into 2 types: essential and nonessential.
Essential amino acids must be gotten from the diet. Threonine, leucine, lysine, methionine, valine, isoleucine, tryptophan, and phenylalanine are included into this kind.
There is also one component, histidine, that is named semi-essential, because it is necessary for growth in children.
