what is another name for a chain of amino acids
In amino acids that have a carbon chain attached to the Î±âcarbon (such as lysine, shown to the right) the carbons are labeled in order as Î±, Î², Î³, Î´, and so on. In some amino acids, the amine group is attached to the Î² or Î³-carbon, and these are therefore referred to as beta or gamma amino acids.
