What is the difference between essential and natural amino acids?

1 year ago

Essential amino acids are those that the organism is not able to synthesize and that need to be ingested by the individual. Natural amino acids are those that are produced by the organism.

There are living species that produce every amino acid they need, for example, the bacteria Escherichia coli, that does not have essential amino acids. Other species, like humans, need to obtain essential amino acids from the diet. Among the twenty different known amino acids that form proteins humans can make twelve of them and the remaining eight need to be taken from the proteins they ingest with food.

The essential amino acids for humans are phenylalanine, histidine, isoleucine, lysine, methionine, threonine, tryptophane and valine.
