2. Essential Amino Acids

Our bodies make up to 11 out of the 20 amino acids needed for life. The ones that we cannot produce are called essential amino acids. We cannot store excess amino acids for long, unlike starch and fat, so we need to consume sources every day. Deficiency in any one of these compounds impairs the functioning of all the other amino acids, so they are all necessary.

The essential amino acids are:

  • arginine
  • histidine
  • isoleucine
  • leucine
  • lysine
  • methionine
  • phenylalanine
  • threonine
  • tryptophan
  • valine
