The eight original essential amino acids are isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. Food sources of amino acids are protein-rich foods. As these foods are digested and assimilated the peptide bonds that link amino acids chains to form the proteins are broken.

What are essential amino acids simple?

Essential amino acids, also known as indispensable amino acids, are amino acids that humans and other vertebrates cannot synthesize from metabolic intermediates. These amino acids must be supplied from an exogenous diet because the human body lacks the metabolic pathways required to synthesize these amino acids.
