Twenty Amino Acids

There are twenty amino acids required for human life to exist. Adults need nine essential amino acids that they cannot synthesize and must get from food. The other eleven can be produced within our bodies. In addition to the twenty amino acids we show you, there are others found in nature (and some very small amounts in us). These twenty are the biggies for our species and defined as the standard amino acids.
