Question:
What is the minimum number of amino acids it takes to form a single protein?


Replies:
There are natural dimers of amino acids. A protein is a chain of amino acids of any length. Sometimes people would rather call short chains "polypeptides", but length is relative. One amino acid would not really be called a protein but single amino acids can have natural biological functions as well; such as the neurotransmitters, glycine and glutamate.
