There are 20 common amino acids that are found in biological systems. These amino acids are:

  • Alanine
  • Arginine
  • Asparagine
  • Aspartic acid
  • Cysteine
  • Glutamic acid
  • Glutamine
  • Glycine
  • Histidine
  • Isoleucine
  • Leucine
  • Lysine
  • Methionine
  • Phenylalanine
  • Proline
  • Serine
  • Threonine
  • Tryptophan
  • Tyrosine
  • Valine

These 20 amino acids form the building blocks of proteins which are essential for the functioning of biological systems.

How many amino acids could be found in the human body?

There are twenty common protein amino acids in your body, of which half can be formed in the cells. The remainder need to be consumed in our diet, as our body cannot make them, yet they are still vital. There are 2 other amino acids very ocassionally used in proteins (only one in humans) meaning that are 21 different protein amino acids in humans. Some biological pathways use other types of amino acids not found in proteins. There are at least six additional ones found in humans, but it would be difficult to determine an exact number.
