Answer : The least number of amino acids in a polypeptide are 10
Explanation :
A peptide is a compound which is formed by joining of 2 or more amino acids by peptide linkage.
Depending on the number of amino acids involved in the formation of the peptide,it can be classified as follows.
1) Dipeptide : This is the shortest peptide chain and contains only 2 amino acids.
2) Polypeptide : This is formed when 10 or more amino acids are joined together. A polypeptide can have 10 to 50 amino acid molecules.
When the number of amino acids are more than 50, then the compound is termed as a "protein".
Therefore we can say that the least number of amino acids in a polypeptide are 10.
