Another term that comes up when we talk about protein nutrition is the term essential amino acid. Our bodies can make quite a number of amino acids from other chemicals that are contained in the body and can convert some amino acids into other amino acids. However, there are some amino acids we are not able to synthesize ourselves. Those particular amino acids and they must be provided to us in our diet. Those amino acids are referred to as the essential amino acids. It's not to say that the non-essential amino acids are not necessary, it's just that it is not necessary for them to be in our diet because other things in the diet can be used to make them.
